Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I was watching a video with mplayer. When the playback was finished I wanted to delete the file in dolphin (.mp4). I think the crash happened between closing mplayer and selecting the file in dolphin.
