Irradiance Map and Glass

[Mudo]

Hi everyone, I'm having some issues with glass and the Irradiance map as the primary ray, that's the second model this problem happened. While using Brute force the render works fine.

If I remove the glass complete from the scene, it render normally.

I'm using high settings with ambient occlusion "on" and irradiance map, changed nothing else.

Anybody got anything similar?
