Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I didn't do anything out of the ordinary, but CWP was not updating prior to the crash. As I was trying to get it to update, it crashed and caused plasma desktop to reload.

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Aborted
