Description luchotres 2012-01-15 09:51:40 UTC
On Mac Snow Leopard.
Libreoffice crashes if you want to change preferences (vg language) or use text fill empty or... various if you have checked on "enable access for assistance devices in Preferences.

It is very  difficult to find out the solution. I think if the bug is not corrected it should be advised to every mac user. I almost give up and leave LO.

Correction
You have to uncheck Enable access for assistance devices

System Preferences > Universal Access > uncheck Enable access for assistance
devices 
(it's the first checkbox on the bottom of the Universal Access preference pane)

MacOS 10.5 leopard - intel
I can't reproduce this bug.

LibreOffice doesn't crash when i change the state of the checkbox "enable access for assistance devices" in preferences.
Comment 2 Petr Mladek 2012-01-26 06:52:51 UTC
I add some MAC users into CC.

Fabien is not able to reproduce this, so it is not a common problem => it should not block the release => lovering the severity a bit.
Comment 3 Rainer Bielefeld Retired 2012-03-05 22:18:08 UTC
Currently this one is not confirmed. Any ideas?
Comment 4 Norbert Thiebaud 2012-03-06 00:09:03 UTC
Can't reproduce (3.5.1)

but then, I don't have any languages installed, and I have no idea what

"use text fill empty or... various"
means...

Hi all,

This has been reported before, with the Assistive Technology options activated, most notably VoiceOver.

Both Thorsten and I have been involved in previous bug reports of this kind, which all got closed in the end because we couldn't reproduce. So while the problem is known, it only occurs on some people's Macs and as yet no one is any the wiser as to where the problems actually lie, but it does seem to be linked to the AT functions provided by Mac OSX.

I have activated "Enable access for assistant devices" on MacOS X 10.6.8 (German) and played around with LibreOffice 3.5.1.2 (Build-ID: dc9775d-05ecbee-0851ad3-1586698-727bf66), but no crashes occur.

@luchotres:
What does "change preferences (vg language) or use text fill empty or... various" mean exacly? Could you please give some steps (1. 2. 3.) you do/did with LibreOffice in order to reproduce the crash?

No offence, I just want to help you but I can't reproduce your problem, just like Fabien, Norbert, and Alex ... If we could reproduce the crash we could help you.
Comment 7 Roman Eisele 2012-07-11 09:12:19 UTC
This is more or less a duplicate of bug 47368, therefore I mark this report as a duplicate of bug 47368. Please continue the discussion on the report for bug 47368. Thank you!

*** This bug has been marked as a duplicate of bug 47368 ***

No "See Also" to bug 47368 necessary, if the present bug is already marked as a duplicate of bug 47368.

Mac Accessibility Related Bugs Survey Results
---------------------------------------------

This report mentions explicitely two ways to crash LibreOffice on Mac OS when “Enable access for assistance devices” is checked:

(A) “if you want to change preferences (vg language)”
(B) “if you […] use text fill empty”

(I can’t extrapolate what other ways are included in “or... various”, sorry ;-)

We have to deal with these two issues separately.


(A)
...
I do not know what “vg” means, but the mention of “language” is probably meant as an example of the application “preferences” “you want to change”. So I take this as a general report about Mac accessibility related LibreOffice crashes which happen when you want to change some settings in the LibreOffice applications Preferences/Options dialog window.

This in turn means that (A) is very probably the same problem as in
* bug 33359
* bug 46981
* bug 51712
* bug 52147
* bug 54282 and
* https://bugs.freedesktop.org/show_bug.cgi?id=47368#c93, item (II).

As I have stated during my ongoing “Mac Accessibility Related Bugs Survey” in most/all of these bugs, this crash has now been fixed by Michael Meek’s patch for bug 47368:
http://cgit.freedesktop.org/libreoffice/core/commit/?id=3234b715b5a6d13ee673b41066eb565706be5ec9


(B)
...
This issue is most probably the same problem as in bug 44471 -- “FORMATTING: Changing character background color causes HANG”. As I have stated now in bug 44471, this issue, while still reproducible with LibreOffice 3.5.6.2, is no longer reproducible in LibreOffice >= 3.6.1 and current master builds. Therefore I have marked bug 44471 as RESOLVED/WORKSFORME.


Results
.......

Given the fact that issue (B) is RESOLVED/WORKSFORME, like bug 44471, and issue (A) was fixed by one of the patches applied in bug 47368, I would suggest that the present bug is correctly marked as a duplicate of bug 47368.

The patch for bug 47368 mentioned above will appear in LibreOffice 3.6.2 and 3.7.0. This means that also issue (A) will be fixed in these versions, while issue (B) is already fixed right now.
