Description Gregor Petrin 2010-08-13 21:49:45 UTC 
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.

Comment 1 Myriam Schweingruber 2010-08-14 17:41:16 UTC 
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.
Comment 2 Jean-Baptiste Kempf 2010-08-14 17:57:35 UTC 
Can you share the backtrace you have with the xine backend?
Comment 3 Gregor Petrin 2010-08-14 20:20:11 UTC 
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 :)
Comment 4 Myriam Schweingruber 2010-08-15 09:52:34 UTC 
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.
Comment 5 Gregor Petrin 2010-08-15 13:42:20 UTC 
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.

Comment 6 Gregor Petrin 2010-08-16 14:08:33 UTC 
Thank you, it worked, openSUSE seems to have update to the fixed version.

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!
Comment 7 Myriam Schweingruber 2010-08-16 14:55:29 UTC 
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
Comment 8 Myriam Schweingruber 2011-04-27 21:32:57 UTC 
Reassigning to the new bugzilla product for better bug tracing of the various
backends. Sorry for the noise.
