I just ran this on Stockfish 1.8 (Mac 10.5, 2 cores) and after loading the first three plies 1. ... Bxg4 2. fxg4 Nxg4, SF thought Black was winning until ply 32, when it found 3. Qe2 =, with a 0.00 score.

I am not sure what to believe here, but this problem may have more to it than meets the eye.

Yep, 1. - Bxg4 is a "brilliant move", but 1. - a4 is a little bit better...
