I'm not completely sure since I never used glass objects with radiosity.
But the black sparkle to be seen at the bottom of the glass object
seem to come from the underlying plane *touching* the bottom of the 
glass (coplanar surfaces error). Lifting the glass object a tiny bit 
(like 1% or less) may help to *disconnect* both objects.
