Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-ARCH i686

What I was doing when the application crashed:
I have shortcuts set for switching desktops (previous, next, up, and down set). plamsa-desktop usually restarts itself, but doesn't always. The bug report dialog doesn't always show either. Happened occasionally with 4.2, but is far more common so far with 4.3.
