Application: dolphin (1.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
I dragged a file from Dolphin into VLC.  Dolphin remains in the "dragging" state even after the file is dropped, so you can get it to do things like multi-select items just by moving around the window.

When I closed Dolphin while it was in this state, it crashed.

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