[pluggo] AU crash in Live

One of the users for one of my Pluggo reports this one time crash in 
Live 6.07 on Mac,  while manipulating a GUI element.  Can someone 
give me a hint as to where in my plug I might look for the source of 
the crash?

To my naive eyes, it seems like it was trying to draw something on 
screen (QD == QuickDraw ??), but I'm really not sure...

Thanks,
Dan
