-- Information about the crash:
- What I was doing when the application crashed:
Every time I win a game Konqueror crashes. It happens since at least Ubuntu 12.04 through 13.04 in newly installed Ubuntu as well as in a system working and upgraded since 2011.

The crash can be reproduced every time.
