Application: plasma-desktop (0.4)
KDE Platform Version: 4.5.85 (4.6 Beta2)
Qt Version: 4.7.0
Operating System: Linux 2.6.37-rc5-hart01 x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I wanted to restart (sound wasn't working) and I started to close the open applications (amarok, krusader, konsole, opera, virtualbox). It then crashed.

- Unusual behavior I noticed:
Sound wasn't working (maybe related to virtualbox 4 beta). I don't have pulseaudio.

-- Backtrace:
