To me, this seems to be a compiler bug. Line 230 is:
   if not FReference.Allocated then Exit;
FReference is an object with a boolean property Allocated. I see no 
reason, why this should give a problem.

Can you try with fpc 2.2.2?

I have no idea, maybe a gtk expert.

For discussion bug, this is the best place. The bug tracker is a bit 
memory (it is easier to look up things), but not the right place for 
debugging.
