Application that crashed: dolphin
Version of the application: 1.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I watched a video in vlc and wanted to drag a second to its playlist. So I took the second with the left mousebutton in Dolphin. Because the playlistwindow did move behind Dolphin I pressed alt+tab to move back to the window. In the 3d-windows-gallery I switched trough seperate windows (Dolphin and Firefox) and when I wanted to select the playlist window Dolphin and vlc chrashed.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
