That was me I guess :-)

Yes, I recall someone giving it a try also (the scene didn't feature the 
child back then) - but IIRC that person "cheated" by having the door 
open much wider...

I'm also using a POV-Ray 3.7 beta feature for the child's clothing 
(diffuse backside illumination), so MCPov is no longer an option anyway.

If I had the slightest idea what kind of error it is, I'd be a good deal 
happier :-)
