    <thetext>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&apos;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
