Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-11-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:

I was tunning a number of applications (Chromium (browser), Dolphin, Kopete, and Okular), with the focus on a Kopete IM window when Plasma suddenly and spontaneously crashed.

Plasma restored itself shortly thereafter (10-20 seconds after the crash).

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