Application: plasma-desktop (0.3)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.1
Operating System: Linux 2.6.31-19-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
I updated KDE version to 4.4. When I restarted the computer I proceed to remove a panel in the bottom of the screen which is similar to the one on the top but smaller. Then, after removal, KDE crashed generating this report.

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