Bug 328283

Application: knights (2.5.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.5
Operating System: Linux 3.11.6-4-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
I was taking back two stages of moves in order to try alternatives. 
- Unusual behavior I noticed:
Suddent crash of the application (but not at once, only after having tried back and forth twice. What was also important: had a heavy systemload in the moment of the crash du to a backup, this might cause the system itself to be less responsive as usual to the requests of the application. 
- Custom settings of the application:
Black and white outfit (I think it is standard) and at least 6 different engines installed. The one that crashed was gnuchess in minimal difficulty - a shame I know, lol.

-- Backtrace:
Application: Knights (knights), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
