just the same as your last crash. problem with var mount or somehow broken cache. expect more of those in all kinds of applications. -> delete all /var/tmp/kdecache-`whoami`/plasma_theme* files, ensure /var/tmp is not full and stay away from bleachbit *** This bug has been marked as a duplicate of bug 305654 ***
