This is a bug with 6.2.  I will guess that your walls have surface normals.
If you remove them, this will render much faster and will look normal.  I
tried to make UVPov use normals with radiosity in 6.2, and it has a bug.
The next version will fix that bug and by default will ignore the surface
normal for radiosity calculations (much faster).

This may be the result of the same bug.  If you have a copy of 6.0 still,
try that.  If not, you'll have to wait for the next release and then let me
know if that fixes the problem.
