Crashes for me already when I merge just two cells with content (!), not even the entire column. Created attachment 110685 [details]
gdb backtrace of crash in master dbgutil build
As not all can reproduce it, crashing operation seems to be on an already deleted object instance, hence the result may depend on system and memory layout.
May actually occur only if accessibility is activated, as SwAccessible... are involved. On pc Debian x86-64 with master sources updated today, I don't reproduce this. (new profile, accessibility enabled). However, I noticed this on console logs: ** (soffice:448): WARNING **: Unknown event notification 35 On linux 64bit debian i also get the above warning... Created attachment 110790 [details] [review] one possible fix The attached works anyway. Lower gets destroyed, upper still points to it and tries to access it from a11y code later on Caolán McNamara committed a patch related to this issue. It has been pushed to "master": http://cgit.freedesktop.org/libreoffice/core/commit/?id=f9eff2a402a4cd28d7dbfb6ce27cbf96b31e576f Resolves: fdo#87199 deregister during destroy as lower of upper It will be available in 4.5.0. The patch should be included in the daily builds available at http://dev-builds.libreoffice.org/daily/ in the next 24-48 hours.

Seems to work anyway, 4-4 review at https://gerrit.libreoffice.org/#/c/13482/ as far as I can tell this has been broken since at least 4.2 and probably always fixed on master Michael Stahl committed a patch related to this issue.

More information about daily builds can be found at: http://wiki.documentfoundation.org/Testing_Daily_Builds Affected users are encouraged to test the fix and report feedback. ok i think i've found out why this crashes... If I'm in Gnome 3 with whatever window manager it uses by default... 1) I open libreoffice 2) create some cells 3) insert content into a column 4) press merge cells and libre crashes THE above process does not OCCUR if i use fluxbox for example... SO its got something to do with the GUI or the window manager... so anyone please confirm The above was confirmed with libreoffice 4.4dev which was stated that the patch had fixed the bug....
