Bug 288236

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:  Kubuntu 11.10, new installation on Vaio VGNFS660P-W laptop:  New activity, add default panel => crash

- Unusual behavior I noticed:  Screen flashed for about 2 seconds with multicolored horizontal lines.  After that, the plasma desktop refreshed and the Crash Reporting Assistant opened.

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