This still occurs in Ubuntu 9.10

Even for one file

1. select a file
2. drag it outside of krusader window
3. move it around a bit, place it above different applications in the taskbar
4. after 5-30 seconds (of dragging) - crash

Application: Krusader (krusader), signal: Segmentation fault
The current source language is "auto; currently c".
