-- Information about the crash:
- What I was doing when the application crashed: accesing Phonon settings in
mulimedia tab in systemsettings

- Unusual behavior I noticed: Pulse folume settings starting up but crashing
and vanashing from screen

and phonon and al backends (Gstreamer) from opensuse repositories (12.3)

The crash can be reproduced every time.
