 From what you wrote earlier, I take it that the biscuits scene renders 
fine.

Can you narrow down which feature causes the problems in the benchmark 
scene? Photons? Media? Radiosity?

It would also be helpful if you could figure out which version was the 
last one that compiled & rendered ok. (If the one after that still 
compiled ok, but rendered bogus, that would also be useful to know.)
