Public bug reported: After an upgrade had problems and seemed X or Unity was always crashing. Got it running in "most-stable" mode. Which means every now and then firefox tabs stop working (affects only the active window of firefox the others remain fully operational). And after rebooting, or logging out the error message keeps on showring.
Have tried to google for a solution but still none so far.
