But note in this case that it is an intermittent problem...not a problem 
with the scene, but a bug somewhere. Something's either uninitialized or 
getting written over. Unfortunately, finding it is likely to be very 
difficult...the problem can be literally anywhere, and will behave 
differently on different machines. It might even be a bad piece of RAM 
in the affected system...but I think other people have reported similar 
things.
