KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:

closing the main window of reconqu causes this crash, no other main windows open, system up-to-date

The crash can be reproduced some of the time.
