Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.8.0
Operating System: Linux 3.1.0-7.fc16.x86_64 x86_64
Distribution: "Fedora release 16 (Verne)"

-- Information about the crash:
- What I was doing when the application crashed:  I had added a top panel and populated it with seven shortcuts and 11 spacers.  I attempted to add the Hardware Temp widget.  This resulted in a space between two of the spacers I had previously added, not an icon.  The display went black for a second and the Crash Reporting Assistant appeared when the display returned.

As I was stepping through the report and adding debug software, per the Assistant, the display blank again and my just-added icons in the top panel were shuffled.  After returning them to the positions I had originally used, moments later they became shuffled again.  Since that time, they have not misbehaved.  I still don't have the Hardware Temp widget successfully installed.

Besides the shortcuts I installed in the top panel, I added an Application Launcher Menu icon without problem.
