Bug 306168

I got a not-always-reproducible crash on exit. The backtrace is:

Application: Konversation (konversation), signal: Segmentation fault

I could not decipher which package was missing to generate a better backtrace.

Some tips:
- I'm not using pulseaudio.
- I'm using the VLC phonon backend.
- During the crash I was using clementine, which in turn uses gstreamer.

This may be a phonon bug, feel free to reassign if so.

Reproducible: Sometimes

Steps to Reproduce:
1. Use konversation.
2. Generate a sound notice.
3. Close konversation.
Actual Results:  
Crash!
