When using a bitmap for color texture in a scene with transparent material with complex ior on, renderer hangs at "computing" stage, and can be stopped only by killing mxcl process.

test conditions :
a 1m square plane with a simple bmp texture.
In the middle of the plane, a transparent cube.
One emitter.
The camera is looking slightly from above, and the plane can be seen through the cube.

Renders ok without dispersion
Renders ok with real ior and disperion on
When enabling complex ior and loadind diam.ior, hangs.
after that, disabling complex ior or changing material is no use, it hangs anyway. Have to resave a clean mxs from plugin and reload.

The preview hangs too

Will send scene to NL
