Bug 269297

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:

I dragged a file from the "quick access" widget and dropped it on the desktop. After releasing the mouse button, the mouse cursor changes to a "not allowed" sign. If i now moves the mouse cursor, the plasma desktop crashes.

The plasma desktop does not crash if i push any mouse button after dropping and than moving the mouse.

Tested with *.sh, *.xml, *.odt files

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