Application: nepomukservicestub (0.2) KDE Platform Version: 4.5.00 (KDE 4.5.0) Qt Version: 4.7.0 Operating System: Linux 2.6.32-24-generic x86_64 Distribution: Ubuntu 10.04.1 LTS -- Information about the crash: - What I was doing when the application crashed: Every now and then, around half of the times I log out from KDE, the nepomuk crashes for no apparent reason. I think it may be connected to leaving amarok playing music when I'm logging out (I don't stop the amarok playback, just log out) The crash can be reproduced some of the time. -- Backtrace: Application: Tymczasowa usługa Nepomuka (nepomukservicestub), signal: Segmentation fault pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:162 in ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S [Current thread is 1 (Thread 0x7f143e938760 (LWP 1543))] Thread 6 (Thread 0x7f1425696710 (LWP 1942)): [KCrash Handler] #6 0x0000000000000000 in ??

Created attachment 51175 [details] New crash information added by DrKonqi nepomukservicestub (0.2) on KDE Platform 4.5.00 (KDE 4.5.0) using Qt 4.7.0 - What I was doing when the application crashed: I upgraded to KDE4.5 (Toshiba Satellite A210) and encountering few problems. One of all are crashes of nepomuk when logging-out, I have just black screen and bug report.

Created attachment 51775 [details] Crash information from DrKonqi, manually saved I have experienced the same crash as in comment #2 once, and I think it is a bit different than the original crash in this bug. I couldn't use DrKonqi directly to submit it because KNetworkManager was already down and I had no connection any more. I use KDE SC 4.5.1.
