Application: plasma-desktop (0.3)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
I had a folder with about 400 images and enabled image previews from the View menu. I then changed my mind and opened the View menu to disable image previews again before Dolphin was done loading all the thumbnails. This is when the panels crashed. 

I have the Window Menubar in the top panel, not in the application window (not sure if this is of importance).

The crash does not seem to be reproducible.

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