so  pd is crashing when it tries to draw an object (most likely: a 
certain object)

since it is unlikely that a "normal object" (no gui, no gop) will cause 
the crash (though not impossible; i only assume so, because if it was 
the case, we would get this bug report more often), so it would be 
interesting to know which graphical objects are hidden in your subpatch.

apart from that, like always: sharing code could help...
