Bug 281854

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 2.6.40.4-5.fc15.x86_64 x86_64
Distribution: "RFRemix release 15.1 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:
I use kde 4.7 on Fedora 15.
On the second monitor when I add the standard panel plasma crashes. I use plasama for desktop computers.

The crash can be reproduced every time.

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