It seems that my particular settings (I've attached the settings file), seem to work. If I remove them then I get the problem too. This is run on one of my work machines so the settings are pretty random...

Well, if I try to use those settings, I get a crash after "resign 1" 
(instruction at 004059C7 trying to read via NULL). A peek at the .gnubgautorc reveals an 
interesting command:
set variation 1-chequer-hypergammon
(Note: I do not have HG database here.)

After removing the line, everything works fine, and...
gnubg accepts and wins a single game.

Many questions come to my mind:
1. Gnubg should not crash, even without HG files.
2. Why do you have that command there?
3. How come it works for you?

Ah - I was looking at a hypergammon problem on this machine... I did say the settings were quite random!
If I remove that line then gnubg wrongly accepts the game.

As to the other questions, I don't think hypergammon is used much so lots of the code is probably doing things wrong when that variation is set. I guess the following should happen/be fixed:

1. It shouldn't crash if you haven't got the correct databases, although the gui doesn't let you pick that option.
2. It shouldn't let you enter positions with the wrong number of chequers.
