Description mlennert 2011-07-06 08:37:02 UTC
Trying to open the .doc file available at


makes LibreOffice hang both on Debian Squeeze and on Windows 7.
Comment 1 Jeffrey 2011-07-07 08:43:17 UTC
Reproduced on LibreOffice 3.4  340m1(Build:12) for OpenSuse Linux. 

Cannot entirely confirm, but I cannot download the attachment successfully. CPU tries downloading, appears on the task bar, then fails.

Successfully opened the document on Windows Vista. Document looks normal--French, some box borders and highlighted phrases. Do not know what can possibly cause the crash.
Comment 2 Rainer Bielefeld Retired 2011-11-09 23:04:38 UTC
[Reproducible] with sample and "LibreOffice Portable 3.3.3  - WIN7  Home Premium (64bit) German UI [OOO330m19 (Build:301  Tag]" 
Also [Reproducible] with "LibreOffice 3.4.4RC2  - WIN7 Home Premium (64bit) German UI [OOO340m1 (Build:402)]"
[Reproducible] with Server installation of Master "LibO-dev 3.5.0 – WIN7 Home Premium (64bit) English UI [(Build ID:  5d1a991-4cb1bac-ca7e6f5-9125509-ce71330)]" (111109)

This problem seems to be different from other "Open document with formula crash" problems I saw, because here also OOo 3.1.1 crashes 

All versions hangf with max CPU load

Fixed in master by this commit:

Comment 4 Michael Stahl (CIB) 2012-02-21 05:14:58 UTC
because i have no idea what that layout stuff is doing,
i have done a bit of regression testing here:
ive tested ~2000 odt files from bugzillas,
in ~120 of those the removed bPosChgd branch was taken,
and out of these i can reliably get different layouts on
these documents:

-  ooo110461-1.odt
   this looks really bad, the OpenOffice.org logos are not visible at all.
   [you may claim that that is a feature, and i will consider a fix
   that replaces them with LibreOffice logos :), but having them
   just disappear is bad]

-  ooo49987-1.odt
   the graphic on page 21 is moved [looks different but harmless]

-  ooo115839-1.odt
   the header graphics are moved
   [there is already another ugly frame on the first page before the fix]

so i'll set this to REOPENED because i think this needs investigation
and we may need a different fix...
Comment 5 sasha.libreoffice 2012-02-21 06:02:13 UTC
master writes this on console when attempt to open:

then appears window where Libreoffice tells that it crashed
Comment 6 Michael Stahl (CIB) 2012-02-21 06:21:56 UTC
don't know how bad the other assertions are, but
this one is implemented with assert(3) and causes an abort:

 SwIndexReg::~SwIndexReg(): Assertion `!m_pFirst && !m_pLast' failed.

it should be fixed on master and libreoffice-3-5
already and i can't reproduce it, can you check that you
have the following master commit and pull/rebuild if not:

Comment 7 sasha.libreoffice 2012-02-21 07:39:46 UTC

3- LibO is frozen and never opens the file

Again [Reproducible] with "LibreOffice German UI/Locale [Build-ID: 281b639-6baa1d3-ef66a77-d866f25-f36d45f] on German WIN7 Home Premium (64bit), 

But (@tommy27):
It's fixed in MASTER 2012-02-08, so a fix can't be in (also see target information in Whiteboard)

The problems you observed with your "more contemporary" Master might be related, So I urgently recommend to open a new bug for that issue (with a reference to this Bug) and close this one. 

Can you please always add the push-date or similar with the Version information? It's impossible for me to see a date version in the Build ID.

I tend to disagree that this is a MAB, again because it affects a single document and cannot be reproduced independent of that single document.

For now I will move it to 3.6 MAB (3.5 is at EOL so no more work is being done on it). We're trying to close the 3.5 most annoying meta bug.

If another QA member agrees with me, we should remove this from MAB list. 

@Reporter - removing from MAB does not mean that your bug will go unnoticed or forgotten. Just in general MAB should affect a lot of users and this doesn't seem to be like that as it's a single document.
Comment 23 Alex Masterov 2013-04-04 07:53:26 UTC
I can reproduce this in LO, LO hangs opening file.

LibO frozen after loading the file

still reproducible on LibO
Comment 27 Joel Madero 2013-08-08 20:29:25 UTC
Removing from MAB list - as mentioned before - a single document showing the problem and one user (lots of QA and devs confirming) being affected. 

Again this does not mean it's not being investigated, it only means that MAB should be bugs that affect many many users - this one does not from what I can tell.

Thanks mlennert and all others for testing and continuing to try to solve this one.
Comment 28 Hans-Gerhard Weinreich 2013-08-28 13:30:06 UTC
Some additional info:

Confirmed with master 2013-08-16_00.24.23 LibO dev 4.1

MS Office 2010 Professional Plus 32bit opens the file without problems.

But the following might be interesting: The issue is reproducible with the current Apache OpenOffice 4.0.0 as well, the symptoms are exactly the same.

My machine: Windows 7 SP1, 64bit
Comment 29 tommy27 2013-08-28 18:21:12 UTC
have you tried removing pages or elements of that .doc file in order to reduce it to a minimal version that still freezes LibO?

the less stuff remains the higher chances to identify what causes the issue.
Comment 30 Hans-Gerhard Weinreich 2013-09-04 18:12:45 UTC
@tommy: so far I was able to delete all contents of pages 1,2 and 4 while leaving page 3 unchanged - this will still freeze LibO. Can anyone with access to MS Office confirm this? Otherwise I could upload the modified version of the file later.

Furthermore the freeze doesn't occur when converting the file from .doc to .docx using MS Office and then opening the resulting .docx file in LibO.

So the issue is most likely to be found somewhere in the .doc filter and caused by some content on page 3 of the document.
Comment 31 tommy27 2013-09-04 19:49:47 UTC
please, upload here the minimal version test case.

This is the file with 3/4 of its contents removed - still causes freeze

There you go, I attached the modified file. As mentioned above I removed the contents of pages 1, 2 and 4.

I left page 3 unmodified; the resulting file still cannot be opened by LibO and causes it to freeze.
Comment 33 tommy27 2013-09-05 23:50:07 UTC
well done Hans. that will make easier for the devs to debug it.
I confirm it still freezes 4.1.1 and 4.2 master build Sept 3.

what about going deeper? you already reduced the document down to 1 page... 
try removing some more elements inside it (text, images, table, whatever...) till the bug can be reproduced.

minimal version containing just a header - crashes

Tommy27: I went the whole way now, it seems like we have it:

I attached a minimal version of the document, consisting of just two blank pages and a header; it causes LibO to freeze. If you remove the header it won't cause any freeze.

Could you please confirm this?

I read about something wrong on layout management but don't know more about this.
I also think that more than the 2 fdo put in see also could be kindda dup or at least related. But I should search on bugtracker to confirm it (or not!).

Michael: any thoughts/related urls about this?
Comment 46 Hans-Gerhard Weinreich 2015-06-22 13:10:08 UTC
Tested with LibO 5.0 RC1 64bit ( (x64)) on Win 7, 64bit: same result, causes LibO to freeze permanently.
Comment 47 Hans-Gerhard Weinreich 2015-10-20 12:22:35 UTC
Fixed in master - tested with LibO Dev 5.1 alpha (x64) / master 2015-10-19_21:22:52 on Windows 7 64.

All versions of the document attached here can be opened and viewed normally, without any freeze.

Can anyone else confirm this? If yes, then I think this can be changed to RESOLVED.

Now I don't know if it can be considered as WFM. Perhaps we should change the title to indicate a perf pb and let this bugtracker opened?

I close as WFM per Comment 47 and my test. Opens from LO 5.0.4.
Perf and layout should be another issue.
