Exactly what I was talking about.

Anyway, seems like problem is of different nature.
Turned out that the problem was that when you have
Scene 1 having a Scene2 as a SET, and render Scene 1,
only Scene 2 is rendered (check attachment, bird and
paper are on Scene1, rest is Scene2 (SET) )

I got confused because I had objects with alpha zero
in Scene1, and thought that was the culprit.

I could reproduce it in a simpler scene with
yesterday's CVS, can't try today's (no bandwidth)
