Bug 341878

Application: konquest (2.3)
KDE Platform Version: 4.14.2
Qt Version: 4.8.6
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux 8.0 (jessie)

-- Information about the crash:
- What I was doing when the application crashed: When won a game using any size of map set, see the score board, and change the size of the score board, the program will crash when clicked OK button of the score board. System is Debian.

The crash can be reproduced every time.

-- Backtrace:
Application: Konquest (konquest), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
