Description Jacques Beckand 2018-10-10 10:08:56 UTC
This bug was filed from the crash reporting server and is br-ef6f4b0c-1f53-418e-983e-0ea6fa2d9762.
=========================================
Writer freezes quite frequently, at random while editing a document, without any specific action which seems to cause the problem. 

The crash report is always the same. Latest is under this URL: http://crashreport.libreoffice.org/stats/crash_details/ef6f4b0c-1f53-418e-983e-0ea6fa2d9762

For info, the crash reason is : SIGABRT

Many thanks for you help solving this very annoying problem.

Document where latest freeze occurred during edition

Herewith the document (fairly simple) during edition of which the latest freeze occurred.
Comment 3 Jean-Baptiste Faure 2018-10-14 15:38:42 UTC
What is the format of your document? odt, doc, docx, something else ?

Status set to NEEDINFO, please set it back to UNCONFIRMED once requested
informations are provided.

Best regards. JBF
Comment 4 Jacques Beckand 2018-10-14 16:02:25 UTC
Attached document is a simple .txt text document. But I've got exactly the same problem with an .odt document. Again this freeze is not systematic, but happens fairly regularly.

Best regards
Jacques
Comment 5 Jean-Baptiste Faure 2018-10-14 16:28:21 UTC
OK. No problem to open this document if I add the .txt extension to its filename.

Best regards. JBF

I didn't try again with that very document. But I still have the freeze and crash from time to time when working on LibreOffice documents. This happens with Calc as well as with Writer. I'm running LibreOffice on Lubuntu 18.04.

Comment 9 Jacques Beckand 2018-12-21 14:38:40 UTC
Hi,
This is a bug which freezes LibreOffice quite frequently in my case, always caused by a segfault in libc-2.27.so

This happens as well with Calc as with Writer. I experience it quite a lot and seemingly, here is correlation between all freeze cases. It looks like happening at random times when using LibreOffice.

See latest crash report: http://crashreport.libreoffice.org/stats/crash_details/20fd21bc-470d-4620-90b6-afc63ec5f44b

OS: Lubuntu 18.04
Comment 10 Jacques Beckand 2018-12-23 21:56:41 UTC
Sorry, I meant "there is NO correlation between the cases where LO freezes". So happens completely at random, with Writer as well as with Calc, whatever the document edited.

Merry Christmas for you and your families!

Basic advice is to reset user profile: https://wiki.documentfoundation.org/UserProfile Please try that. 
Other advice is to upgrade to latest Fresh, which is 6.1.4.
Please write if the freeze didn't happen with some older version. If you don't remember, you may downgrade LO to 6.0.7 and try. 
All this comes as we cannot do something without reproducible steps.
Comment 13 Timur 2018-12-27 11:15:11 UTC
Not sure if this can be related to regression commit found in Bug 121439 (that has reproducible steps). We'll see if it's fixed.

Many thanks Timur,

OK I'll do that and tell you.
> Other advice is to upgrade to latest Fresh, which is 6.1.4.
The problem happens on 6.1.4 as well.

I know for sure this didn't happen with LO 5.x.x For 6.0.7, if the user profile reset didn't fix the problem, I will downgrade to 6.0.7 and test.
> All this comes as we cannot do something without reproducible steps.
I understand. This is the big problem with such bugs happening at random, in any situation, without any obvious coherent cause.

Thanks again and a happy new year to you and the whole LO team.
Comment 15 Jacques Beckand 2018-12-28 12:45:51 UTC
Resetting the user profile didn't fix the problem.
So I'll proceed to the next step: downgrading to version 6.0.7
Comment 16 Jacques Beckand 2018-12-31 11:19:09 UTC
Hi Timur,

After having reset my user profile, which didn't fix the problem, I downgraded LO to 6.0.7 as you proposed. And...the problem doesn't happen at all on that version.

At last an important information: this bug appeared as of version 6.1

Many thanks again for your help
Jacques
Comment 17 Jacques Beckand 2019-01-07 09:48:59 UTC
I installed (on Lubuntu 18.04 computer) LO 6.1.4 via the Snap installation format, instead of the .deb files of the download page of the LO site.

The problem seems fixed with that kind of installation. Snap does not use the common libraries stored in the system, but instead installs everything needed to run. So it might well be that the problem lies in a common dependency library rather than within the LO .deb packages themselves.

I'm not a computer specialist, but I hope this clue helps detecting the source of the problem.

Best regards,
Jacques

Does it happen with LibreOffice 6.2.0.1 from https://wiki.documentfoundation.org/QA/GetInvolved#Test_Pre-releases ?

My Writer has crashed for several times:

http://crashreport.libreoffice.org/stats/crash_details/555911ce-21ac-4bc3-b0e4-170ede1e04db

版本:6.2.0.2
組建 ID:2ce5217b30a543f7666022df50f0562f82be0cff
CPU 執行緒:4; OS:Linux 4.15; UI 算繪:預設; VCL: kde5; 
語言地區:zh-TW (zh_TW.UTF-8); UI語言:zh-TW

The crash report directed me to this one.

It crashed too often for me...

crashreport.libreoffice.org/stats/crash_details/c1841129-d9d8-4d04-8dc2-46a9f4c484d6

The same version / hardware info as the last comment.  Might be kde5 backend related as well?
Comment 21 Xisco Faulí 2019-01-14 09:59:42 UTC
Hi Franklin Weng,
So it crashes opening the file attached or how does it crash ?
Comment 22 Jacques Beckand 2019-01-14 10:30:22 UTC
To answer Xisco's question,

In my case, LO does not crash but hangs. As far as I can remember, the hard disk is 100% busy during the freeze. I need to kill the task at the OS level (Lubuntu) to get out of the freeze. 

When does this happen ? Really at random. Whatever the document, whatever I'm doing with it. I could not correlate the bug with a typical situation. Sometimes I can work one hour without problem, sometimes it happens after 10 min,...

As said earlier, till now I didn't experience the problem with a Snap installation of LO. This might be a clue, but due to its random nature, I cannot guarantee it means that the problem disappeared.
Comment 23 L P Luigi Espenlaub 2019-04-17 03:32:32 UTC
It will take some more testing but the answer seems to arrived just in time. LibreOffice 6.2.2.2 is available in the Ubuntu Software Store, 

Updated 04/17/2019 as a snap.

** For some reason, I had to uninstall my 6.1 completely for the 6.2.2.2 snap to successfully install.**

Note: if you have any special dictionaries or templates it will be easier add them to any upgrade by copying them to a folder for each in the home directory. Then add paths to them in options > paths after the new install]

My first test was to try Help > LibreOffice Help F-1 which crashed in 6.1 every time then proceeded to crash while submitting the crash report.

Result: No crash, and local help loaded.

It will be a couple of days before I will know if this fixes the un-predictable crashes I have been experiencing in this module.

Thanks for the 6.1 snap hint. Couldn't find it, then this updated snap just appeared.

Here's hoping!
