Reported using DrKonqi 1276074 1 thomas.luebking 2012-07-14 07:41:30 +0000 Bleachbit invalidates shared memory. Google for it, there are tons of bug reports about this. -> Don't use bleachbit (it's snake oil anyway, see eg. http://lwn.net/Articles/313679/) or at least do not let it override files (just deleting them is ok, but the other way corrupts random other applications if done on the wrong files) *** This bug has been marked as a duplicate of bug 254741 ***
