Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was shutting down the computer and plasma crashed. This happens consistently, and when the bug reporter comes up, it doesn't allow you to authenticate to install the debug symbols. You have to install them separately and wait for the crash again to report it.

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