--- Blender version with error, and version that worked ---
tested and failed with Blender 2.66 and Blender 2.66a


--- Short description of error ---
With the internal renderer an SSS material renders (and appears in the material preview window also) black.

--- Steps for others to reproduce the error (preferably based on attached .blend file) ---
Create a material with the internal renderer. Use the SSS.
Make the SSS Texture scatter parameter bigger than 0.000
Add an image texture to the material (any image, any format, .jpeg, .png does the bug)
In the Color tab of the texture set the contrast to 1.2 or higher,
and the Saturation value of the textures higher than 1.200 it becomes black !

Tweaking any of those two values higher than 1.2 makes the SSS (and reflections of the SSS) black...
