Hmm... perhaps when it calculates radiosity, some of the vectors start from
a place that is swept out by the rotating object.  When the object reaches
this point, the rays (presumably reflected off the object itself) either
hit the inside surface or some outer surface of the object (I cant imagine
the shapes needed for this to happen...).  Turning off shadows might help,
or calculating radiosity with a larger, placeholder object (an object that
will always contain the rotating one).  I need to know more about the scene
to help any more than this, though.  And it is just a theory.

A frame of the animation as it is supposed to behave and one during the
buggy 30 seconds would be useful.
