[PD] GEM renderchain issue / pd crash

[florian grassl]

hi everybody,

i have got a problem with getting alphablending right in GEM 0.87. i have a background image or video going on ( [pix_movie] and [pix_image]) and normal geos in the foreground. by now the renderchain is set to i.e. 
[gemhead 80]
|
[pix_movie]
|
[gemlist(

and

[gemhead 50]
|
[cube]

as far as i understand, this prevents the cube from being "seethrough" to the video.
but if i set the cube´s gemhead later (nr above) the movie´s one, i make pd crash.
("stopping: caught an exception")
is this a known bug with the pix object? using the geos only, all works fine.
any suggestions?
cheers for your help in advance,
flo

spec: xp / GEM 0.87 / pd 0.37.0
