Trouble with multipass mental ray rendering (Glowing Shave Shaded Fur?)

[marlis-fleischmann]

Hello guys,
I am yet unexperienced regarding rendering and I'm encountering severe trouble when trying to render my animation in different passes.

 The furr (using the Shave Shader Plugin for this one) appears to glow. I have no idea why, any suggestions?
