Bump map not visible through blend refractive material

[maru]

Here's my observation:

Bump map is not visible on objects seen through glass made of blend materials. Same happens for single-sided geometry and "thin" refraction model. This doesn't happen for diffuse.

Don't know if it's a serious issue but still happening with newest build.
