Yeah, I had one of those myself.  POV-Ray gives this creepy feeling to scenes
where light comes solely from the outdoor through a semi-opened door... :)

I think the light coming through the corner of the wall and floor can be
suppressed by having actual walls with thickness, like a scaled box.

That, mainly.  But I believe error_bound should actually go up a little:  it
should also be faster to test.  Try with error_bound .8 first.
