Application: knotify4 (4.0)
KDE Platform Version: 4.4.1 (KDE 4.4.1) "release 227"
Qt Version: 4.6.2
Operating System: Linux 2.6.31.12-0.1-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
knotify crashes when using gstreamer backend.
Many many crashes lately. Every single time knotify is used to ring the bell.
Also tried switching back to the xine backend, and that's no better.

The last few days have been super unstable in KDE 4.4.whatever with respect to sound. A week ago it was pretty rock solid. Not sure what changed!



The crash can be reproduced every time.

 -- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
