-- 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
