Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.32-25-generic x86_64
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was rearranging songs in an Amarok playlist. My second monitor (not the one I was editing in) went black and I received  a Plasma crash notification.

- Unusual behavior I noticed: secondary monitor screen went black for a moment. Amarok window in primary monitor went from full screen to just the top half of the screen.

-- Backtrace:
Application: Plasma Workspace (plasma-desktop), signal: Segmentation fault
