Application: kjumpingcube (1.2)
KDE Platform Version: 4.8.5 (4.8.5)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-57-generic x86_64
Distribution: Ubuntu 12.04.3 LTS

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

1.  Playing as second player (computer as first) on 10x10 expert
2.  After winning game I click to close the "you have won" window.
3. Then click to close the game window.
4. Game crashes instead of closing.

With computer as first player as soon as you close the "you have won" window, it starts up a new game.  The crash is triggered if you try to close before the computer (as first player) finishes its first move. It is very easy to trigger this when playing as second player because you usually will want to close after completing a game which is very likely to trigger the crash.
