Bug 291229

Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.3 (KDE 4.5.3)
Qt Version: 4.7.0
Operating System: Linux 2.6.39.4 x86_64
Distribution: Ubuntu 10.04.2 LTS

-- Information about the crash:
- What I was doing when the application crashed: I was adding a fourth icon to the quick start object/widget.

- Custom settings of the application: The panel is not maximized and is on the bottom left corner with the quick start icons in vertical position (the panel high is about 40 or more pixels). THE PROBLEM WAS FIND IN BACKTRACK 5 R1 (based on Ubuntu 10.04 of course).

I don't know if it is a bug already fixed, but i posted it because in my stable version of BackTrack I think that there shouldn't be bugs.

Ciao from Italy!

The crash can be reproduced every time.

-- Backtrace:
Application: Spazio di lavoro di Plasma (plasma-desktop), signal: Segmentation fault
