Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
* What I was doing when the application crashed:

- I wanted to add MP3s to my playlist.
- I selected multiple files (MP3s).
- Started dragging.
- Dragged to (AUTO-HIDING) taskbar panel in order to bring it to foreground.
- ALT-TABbed around a little, to see something in another window, while not releasing the mouse button yet, and then back again at my application (VLC).
- Released mouse on application's drag&drop area in order to DROP my selected files there.
- Dolphin crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
