Ah thanks for the further clues. I'll try this sort of thing. That doc 
wasn't in libbonobo-2.0.1.tar.gz which was what I was using for a source 
code reference.

All the other issues I raised in that email are fixed now. (Dom took out 
the menu bar.)

I'll remove the unref work-around as soon as I get to the bottom of the 
ref counting  issue. Thanks for the help. I must say that I find bonobo 
pretty cool :-) 

Cheers

Martin
