Version:           0.1 (using Devel)
Installed from:    Compiled sources

Application: plasma-netbook (0.1)
KDE Platform Version: 4.3.85 (KDE 4.3.85 (KDE 4.4 Beta2))
Qt Version: 4.6.0
Operating System: Linux 2.6.32.2-14.fc13.i686 i686
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Steps to reproduce this:
1. login in a clean desktop
2. Move to "Search and launch" page
3. Start konsole (it opens maximized, top bar is hidden)
4. maybe wait a few seconds
5. move the mouse to the top so that the hidden plasma bar should be shown
6. wait for the crash


For clarification: I'm not trying this on a netbook (no space for debug packages) but on my normal workstation.

The crash can be reproduced everytime.

 -- Backtrace:
Application: Plasma Netbook (plasma-netbook), signal: Segmentation fault
