Bug 274239

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Ordinary desktop use. I was listening to a radio stream using amarok.

- Unusual behavior I noticed:
Heavy slowdown. This has happened again to me and it was because of a memory leak in Amarok so swap memory was used. I went straight to kill amarok (killall -9 amarok) and plasma crashed.

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