Qt Version: 4.7.1
Operating System: Linux 2.6.37.6-0.7-default x86_64
Distribution: "openSUSE 11.4 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: Entering a path for a KMAIL attachment. There were no signs of problems before entering the path. Note that the crash occured before the path was completed.

The crash can be reproduced some of the time.
