Bug 272903

Application: dolphin (1.6.1)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-9-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: Copying files between tabs by drag and drop via Dolphin

- Unusual behavior I noticed: So far all 3 times it has happened the path has expanded as I held the files to be copied over the tab for too long. After clicking blank space to get the list of directories to go away - Dolphin crashed.

The crash can be reproduced some of the time.

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