Bug 292177

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Linux Mint 12 Lisa

-- Information about the crash:
- What I was doing when the application crashed:
using Wine in the backgroud installing 'Football Superstars'. I had selected show desktop a couple of times, then KDE crashed. This then led to KDE re-starting by itself.

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