Reported using DrKonqi 1162208 1 thomas.luebking 2011-09-12 22:59:44 +0000 Do you happen to have used BleachBit? 1162257 2 blackstorm010 2011-09-13 07:21:14 +0000 Yes...I've used bleachbit before this crash....is this the problem? BleachBit doesn't support KDE? 1162308 3 thomas.luebking 2011-09-13 10:49:59 +0000 Yes, versions before 0.8.7 used to shredder the files that serve as KDE's shared memory backends, what's as good or worse as invalidating the processes memory (in contrast to simple deleting, what's just fine) See comments at the dupe and upgrade BB or add the files to the whitelist. In general i'd be rather extra careful with software doing automated deletions and worse: overwrites of "superfluous" files... *** This bug has been marked as a duplicate of bug 271889 ***
