Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
Amarok was running before the shutdown, so all these Amarok-related Plasma crashes may be related/identical to this one.

- What I was doing when the application crashed:
Shutting down

The crash can be reproduced every time.

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