Qt Version: 4.7.0
Operating System: Linux 2.6.35-30-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Just reorganiszing several dozend of pics in other folders, creating new directories, ersing double pics etc to create a news collection of pics. 

- Unusual behavior I noticed:
DK is slowing down considerable (8GB memory)

The crash can be reproduced every time.
