Bug 273053

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.3 (4.6.3) (Compiled from sources)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-gentoo-r3 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:
I came back after being a ~ 90 minutes afk, found amarok freezed, and eating up 100% cpu load, so I killed it via kwin (right click on X, wait, klick on terminate).
This termination also killed the plasma desktop, and this behaviour is something I get recently quite often.

Please note, I am on kde 4.6.3 and the possible duplicate I marked is from far earlier, however, the infos looked similar.

The crash can be reproduced some of the time.
