the problem was really on the pd-side of the object: the list-callback 
was expecting (void*, int argc, t_atom*argv) instead of (void*, 
t_symbol*s, int argc, t_atom*argv)
this makes a huge difference when receiving lists :-)

the really tricky objects in the GEM-wrapper are those that expect more 
complex data than just (small) arrays of floats. e.g. textures,...
nobody has taken care of them yet :-)
(i will eventually do so, when somebody comes up with: 
"[GEMglDrawPixels] crashes...")
