Ouch, I've just reproduced the missing shadows with OSG master and 3.6
branch.  At this point I don't have any ideas.  I am really not sure
if I've tested this particular combination, must be quite a while if I
did...

I will look into it.  In general I wouldn't recommend using
ShadowVolumes as the computation of shadow volumes themselves is not a
trivial task for general purpose geometry, the image based shadow
technique are easier to get to work in more general scenes.
