Hello Ulrich Maasmeier,
thank you very much for your bug report!

It's a pity that LibreOffice causes so many crashes for you. However, it runs without crashes on many other machines, so we need to find out what makes the difference, i.e. why LibreOffice crashes so often in your installation.

The first two things to check are:

1) Do you have any accesibility features enabled? Apple's accessibility features like "VoiceOver" or "Enable access for assistive devices", which get enabled in "System Preferences > Universal Access" (in German: "Bedienungshilfen"), are known to cause many crashes in LibreOffice. So please try to disable any accesibility features. Compare, e.g., the similar issue bug 47368.

2) Can you please try running LibreOffice with a brand new LO user profile (see http://wiki.documentfoundation.org/UserProfile)? This seems to heal many serious problems, cf. the brand new bug 51323.

Thank you very much for trying this out (and please report the results here, too)!

The attached screenshot shows the setting for "assistive devices" activated.

THIS seems to initiate the bug while adding a text color to marked text.

IF set to OFF, the bug disappears in a test series of about 10 aimed provocations.

Due to comment #3, I mark this bug as a duplicate of our famous bug 47368, just
like bug 47569 and other bug reports about crashes on MacOS with "Universal
Access"/accessibility enabled. Also updated the summary accordingly.

@Ulrich Maasmeier:
Thank you very much for your report of your results!

Mac Accessibility Related Bugs Survey Results


The original description is not completely clear to me (does it mention one or three ways to crash LibreOffice?), so I concentrate on the single issue mentioned in comment #3:

> adding a text color to marked text

This is more or less the same issue as in bug 51686 (and others). This issue is IMHO fixed in LibreOffice >= 3.6.1 -- even with “Enable access for assistive devices” checked and RightZoom running, I can no longer reproduce it. As explained in bug 51686, the fix seems to have happened somewhere in the 3.6 development process, even _before_ bug 47368 was fixed. Therefore the present bug can not be a duplicate of bug 47368.

Therefore I mark this bug as a duplicate of bug 51686. If any further discussion is needed, this should probably be done in the report for bug 51686.

What about LibreOffice 3.5.x?

Bug 51686 (and therefore the present bug) is still reproducible in LibreOffice Therefore you could ask to fix this bug also in the 3.5 branch where it is still reproducible, but the chances are bad: we don’t know which commit(s) have fixed the issue, therefore it is not possible to backport that commit(s).

Additionally, there is a workaround suitable for most users (disable any Mac
accessibility features and accessibility-related utilities).

Therefore, this bug will probably not get fixed in the LibreOffice 3.5 branch,
sorry. So please do NOT reopen this bug report just because this bug was not
fixed in LibreOffice 3.5.x ;-)

Thank you!
