[PD] gem .87 bug

I've been playing with the pix_video under linux and have noticed a bug. 
I have two objects in my scene. I want the video plane behind a 
translucent object. If I change my gemheads so that the video plane is 
behind the translucent object (so the video is rendered first, ie gemhead 
1) PD segfaults when I render. If the translucent object is on gemhead 5, 
then If I put the video on gemhead 1,2,3,4 then I get the segfault, if I 
set the video to render after the translucent object (gemhead 5,6,7,8 
etc) then there is no segfault, but obviously the object is no longer 
translucent. 

Does this basically mean that one can't render video behind an object 
which calculates alpha? 

Let me know if you need more info, if I should send an example patch. 

Thanks
Ben
