Normal bump (tangent) not working behind opacity-mapped object

[ruud3dv]

The girl in front is a simple plane with a black/white opacity map.
Behind the transparent part of that plane, the bump isn't showing properly on the flowerpots.

Left: no bump
Right: normal bump map, tangent method

Try using the VRayNormalMap, it should work better.
