Application: gwenview (2.4.3) KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 3" Qt Version: 4.6.3 Operating System: Linux 2.6.34.7-0.7-desktop x86_64 Distribution: "openSUSE 11.3 (x86_64)" -- Information about the crash: Sometimes gwenview crashes when I close it too fast. Consider the following scenario: 1. I open some image file like photo in a folder containing lots of other pictures. 2. When I finished with this picture, I press Esc and gwenview turns to the gallery mode and tries to show thumbnails of all pictures in this folder. 3. I immediately press Alt + F4 to completely close the application. 4. Gwenview crashes. The crash can be reproduced some of the time. -- Backtrace: Application: Gwenview (gwenview), signal: Segmentation fault [Current thread is 1 (Thread 0x7f06b9c0d760 (LWP 11183))] Thread 2 (Thread 0x7f06acd80710 (LWP 11202)): #0 0x00007f06b5639eb4 in __lll_lock_wait () from /lib64/libpthread.so.0 #1 0x00007f06b563745c in pthread_cond_wait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #2 0x00007f06b8c3bd23 in ??

I also made it to crash with trunk after some tries. Unfortunately the backtrace is not that helpful. I supose that when closing Gwenview the running threads have not the time to cleanup. Btw. with the version you are using, is the backtrace always the same?
