There's some sort of problem with endgame evaluations. I'm using version 0.13.0.
If I setup the opponent with one checker on pip 23 and one on 24, and my 2 checkers on pip 2. I have the cube, and it's my turn to roll. GnuBG's suggested cube decision is redouble, take. And sure enough if I double, gnubg takes the cube. This is in a 7 game match with a 0-0 score. I agree with the double suggestion, but gnubg should not take the cube. I have a better than 94% chance of winning. I think gnubg is estimating the odds at around 72% or something though.

I'm new to using gnubg, but not matter what skill settings I use I get the same result.

An "Alert: Wrong double" is reported in exported evaluation when doubling to end the game. The result is clear: Doubler will win no matter what the throws are, and opponent has checkers off.

See game 7 in the attached .mat file and evaluation
