I wonder if engines could convince rybka in games that she is wrong? I found only 2 games with this position in the CEGT games and rybka is winning with white and black(I also give analysis by rybka slighly positional after the games. Here are the games I think that it can be productive if you comment the CEGT games and tell us about the mistake of engines and why they lose better positions(assuming that black is really better). Note that I claim nothing about the position. My first impression is also that black has better position but I consider myself too weak player to trust my first impression.
