KDE Platform Version: 4.10.5 "release 1"

-- Information about the crash:
My king was checked by a knight. Although I could eat the knight with a queen, the move was not allowed. Another illegal (not removing check) queen move was allowed, which when played caused the program to crash.
GNU Chess, engine, very easy level.

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