Application: plasma-desktop (0.4)
KDE Platform Version: 4.9.5
Qt Version: 4.8.3
Operating System: Linux 3.5.0-17-generic i686
Distribution: Linux Mint 14 Nadia

-- Information about the crash:
- What I was doing when the application crashed:
I had 2 volume controllers on my toolbar, Veromix and KMix. I closed KMix and kept Veromix open. As soon as KMix closed, the entire Plasma desktop crashed.

The crash can be reproduced some of the time.

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