*** Bug 233660 has been marked as a duplicate of this bug. *** SVN commit 1115720 by dkazakov: Fixed an Q_ASSERT(!m_numTiles) bug There was a race condition in a copy-constructor of the hash table. The source table should have been locked first to get a safe clone.

Application: krita (2.2 Beta 1) KDE Platform Version: 4.4.1 (KDE 4.4.1) Qt Version: 4.6.2 Operating System: Linux 2.6.32.9-70.fc12.i686 i686 Distribution (Platform): Fedora RPMs -- Information about the crash: This assert appears while painting. It sometimes needs lots of strokes to happen, text brush seems to be good to trigger it. I check the value of m_numTiles and it's usually between one and three when asserting. The crash can be reproduced every time. -- Backtrace: Application: Krita (krita), signal: Aborted [Current thread is 1 (Thread 0xb77c9b50 (LWP 26713))] Thread 3 (Thread 0xb7469b70 (LWP 26714)): #0 0x00bce416 in __kernel_vsyscall () #1 0x00c13c45 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #2 0x060f2b7f in QWaitCondition::wait(QMutex*, unsigned long) () from /usr/lib/libQtCore.so.4 #3 0x060ef32d in QSemaphore::acquire(int) () from /usr/lib/libQtCore.so.4 #4 0x00dfff6a in KisTileDataPooler::waitForWork (this=0xf98ba0) at /home/sven/kde/src/koffice/krita/image/tiles3/kis_tile_data_pooler.cc:133 #5 0x00dfffd9 in KisTileDataPooler::run (this=0xf98ba0) at /home/sven/kde/src/koffice/krita/image/tiles3/kis_tile_data_pooler.cc:162 #6 0x060f1cdf in ??
