We are sorry, this is triggered by a commit made recently. The backtrace you post shows you are using the VLC backend, not xine, and I am pretty sure that I can't reproduce this with the Xine backend. Can you share the backtrace you have with the xine backend? Xine doesn't crash, but the sound coming from the speakers (e.g. when using the 'Test' command in the Phonon configuration) is like watching a quiet, slow motion, underwater video :) Which has nothing to do with this crash... A fix has been committed to the vlc-backend (http://gitorious.org/phonon/phonon-vlc/commit/bcad3f673d15bd5e19c379a017ce9dec0ebaa923), you should upgrade as soon s OpenSuSE provides a new checkout. This works for me now. Please file a separate report for the Xine backend. Ok, thanks for all the help! Will report back how it goes with the openSUSE update.. Should I report the Xine bug to KDE list as well (as Phonon related), or do you recommend another place? BTW, I did manage to get xine to crash, via Amarok :) Don't know if it's relevant as Xine doesn't work properly anyway, but here's a back trace.

The audio problem turned out to be the fault of my speakers, not software, now I just have to reproduce that Xine backend bug with Amarok :) Again, thanks! Thank you for the feedback. The backtrace you provide in comment #5 is not a Xine crash, but an Amarok crash, already reported in bug 245513. A fix is available in the upcoming Amarok 2.3.2 beta 1 Reassigning to the new bugzilla product for better bug tracing of the various backends. Sorry for the noise. |
Application: kcmshell4 () KDE Platform Version: 4.5.00 (KDE 4.5.0) Qt Version: 4.6.3 Operating System: Linux 2.6.34-12-desktop x86_64 Distribution: "openSUSE 11.3 (x86_64)" -- Information about the crash: - What I was doing when the application crashed: It happens every time the system tries to play a sound. I get many KNotify errors when there's a popup, this particular backtrace is from the phonon settings application when I press the 'Test' button. I tried two different backends (VLC and xine) and it happened with both. My sound had worked before in this machine (but it is a relatively new install, so it only worked a couple of times). The crash can be reproduced every time. -- Backtrace: Application: KDE Control Module (kdeinit4), signal: Segmentation fault [Current thread is 1 (Thread 0x7f49690ec760 (LWP 11338))] Thread 2 (Thread 0x7f491b15e710 (LWP 11344)): #0 0x00007f4967a9239c in pthread_cond_wait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007f4952943cc2 in LoopRequest (data=0xac88b0) at playlist/thread.c:539 #2 Thread (data=0xac88b0) at playlist/thread.c:586 #3 0x00007f4967a8da4f in start_thread () from /lib64/libpthread.so.0 #4 0x00007f496687d82d in clone () from /lib64/libc.so.6 #5 0x0000000000000000 in ??
