Do you have "media on" in your radiosity block?

If so, it might be worthwhile tuning off radiosity->media interaction 
and seeing if it still happens.

I've found that using scattering media with radiosity (and "media on") 
to be prohibitively expensive and artifact prone, and have given up on 
it.  My time is better spent tweaking the scattering media to interact 
properly with normal point light sources to get the desired effect.
