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 2.6.31-23-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I was using KPackageKit as "Add and Remove Software" from System Settings to scan for new updates. All of a sudden, I got a requester telling me Plasma Workbench had crashed. Sorry, that's all I know.

BTW, I tried to add some debug symbols that were missing, but I keep getting a requester telling me KPackageKit can't get a lock. (I've seen some emails on the Kubuntu list saying the servers seem to be down.)
