Reported using DrKonqi 964219 1 frank78ac 2010-05-19 14:48:45 +0000 Thanks for your report! The backtrace indicates that there is a memory corruption problem because there are simultaneous malloc/free calls in different threads at the time of the crash (I've already seen a couple more backtraces which show this pattern). Such issues are quite hard to debug, unfortunately, because the problem could basically be anywhere... 1005116 2 peter.penz19 2010-08-16 19:43:55 +0000 *** This bug has been marked as a duplicate of bug 235166 ***
