Bug 285862

Application: plasma-desktop (0.4)
KDE Platform Version: 4.7.3 (4.7.3) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0.3 x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I clicked on a grouped item of Kate files (I think, the first click which unfolds the group) and Plasma suddenly crashed.

-- Backtrace:
Application: Оболочка Plasma (kdeinit4), signal: Segmentation fault
