Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.8.0
Operating System: Linux 3.1.6-1.fc16.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I had just closed KMenuEdit and had selected the KMenu by clicking on the Fedora Icon in the bottom right of the screen.  The screen went black momentarily and then came right back.  Everything else is working as far as I can tell.

This instability of the environment is represented by this result quite often.  I am very worried about long term reliability.

Thank you.
