The last line indicates to me that you're trying to render a scene with 
SSLT.

Note that the SSLT feature is still highly experimental, with known 
bugs. I suspect that your SSLT texture has a pigment with some zero 
colour component, a situation SSLT can't deal with. That would be 
consistent with what you see.
