Application: plasma-desktop (0.3)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.35-22-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I was upgrading to the version 11 of Kubuntu. First it gave me an error saying that the Upgrade manager didn't have exclusive lock on OS as another Kubuntu package manager was open. (I didn't open it and certainly I didn't know it was working in backgroud).

- Unusual behavior I noticed:
After exiting the Package Manager, the backgroun turned black, screen froze for a couple of seconds and then I got the crash message

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