Hm, when reading Andrews mail, I thought "Yeah, I had that too.".

Although in my case it was especially weird - I had a scene where one object 
had a face material that added Illumination (made it "glow").
When I put a material in the Root level, everything worked fine; this material 
only altered Color, not Illumination, so the face materials effect was still 
clearly visible.
When I changed the color in the root-level material though, the scene wouldn´t 
render, showing the r3freng 404 error message with a hint to the face material.
Changing the color another time didn´t do any good, but going back in the 
history to the point where I had not yet changed the color originally the scene 
did again render without an error.

Seems to me like there are indeed a bunch of independent bugs tied to r3freng.
Perhaps they have a common base, perhaps there is some glitch in the code or 
some basic error somewhere?
Those totally different situations in which this error occurred however give me 
the feeling that there is some general problem with (or within) r3freng.
