I have intermittent problems running LibreOffice 4.1.1.2 (from the PPA) on Precise 12.04.03. Sometimes when I am either opening or closing the document, the screen flashes and the unity panel disappears.
I am unable to Alt-tab between windows and sometimes my keyboard is not responsive (although Alt-Fx is able to get me to a console login).
if I keep a terminal window open, I am able to close windows down using my mouse and restart unity from the command line (if my keyboard is responsive).
Any ideas on a fix?
I purged the libreoffice-gtk package as per suggestions in other posts, to no effect.
In addition, when I run unity from the terminal, the crash generates these messages (which is meaningless to me, but may help others):

UPDATE 2: I suspect my issue is related to this bug, as I un-maximised the screen and have not had a problem. No workaround available yet, it seems : https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/829384
