When using radiosity sharp corners (i.e. "empty" box) are often very 
bright. Is this a bug, or not?

IMHO such efffect apeare also in nature, when walls are quite "reflective" 
(especialy diffuse >= .80) and have flat color (in pov - just simple 
pigment rgb .9 for example). 

The reson why in nature we don't this efect so much is because
1) wals arent totaly flat (small normal)
2) wals often don't have such idealy 1-colored surfaces
