Application: dolphin (1.6.1)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-12-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
Copying files from one file to another by drag and drop with two dolphin windows open.  I found that when I right clicked on the file to copy it and then pasted it, this solved the issue but when i tried to copy the file by dragging and dropping, this caused it to crash most of the time.

The crash can be reproduced every time.

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