Bug 306177

Application: dolphin (2.0)
KDE Platform Version: 4.8.2 (4.8.2)
Qt Version: 4.8.1
Operating System: Linux 3.0.0-13-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was moving files around to a sub-folder by dragging and releasing on the folder I wanted to move to.
When I released the mouse button, I didn't yet see it but I had already triggered the delayed reaction of entering the sub-folder on long hover, so when I released the mouse mutton, dolphin was already busy rendering the sub-folder. I saw the drag menu (move to, copy to, link to, cancel) being drawn, and then Dolphin crashed.

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