dolphin (1.6) on KDE Platform 4.6.00 (4.6.0) "release 6" using Qt 4.7.1

- What I was doing when the application crashed:

I had just had Cinlerra installed (video edittor) and I was trying to drag and drop a video into the application, other applications were running (firefox, thunderbird)

- Unusual behavior I noticed:

When I drag an item, its icon follows the curser until i drop it. But in the described case the icon disappeared as soon as i hovered the curser over the desired to drop-in application, and when i dropped the video, dolphin crashed.

- Custom settings of the application:

dolphin (1.6.1) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

I was also dragging to VLC (a folder in my case). Dolphin was in column mode, in case it is related.
