Description itayshom 2013-11-01 15:28:37 UTC 
Application: knights (2.5.0)
KDE Platform Version: 4.10.5 "release 1"
Qt Version: 4.8.4
Operating System: Linux 3.7.10-1.16-desktop x86_64
Distribution: "openSUSE 12.3 (x86_64)"

-- Information about the crash:
I was playing white against GNU Chess very easy level. After making a move the opponent doesn't move for a long time (from past experience I know it could be hours at least, this is also a bug I guess).

I pressed pause, then unpause again, and the program crashed.

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

Pausing and unpausing works well here with GNU chess. Please give it another try with the current code.

There is currently no pause/unpause for UCI-engines. I'll add it soon.
