I'll try to fix it later today.  Zoo first.  The example lives in a  
Svn repository for a reason -- I'll cut branches of it to track  
cleaner versions against non-Leopard baselines of RubyCocoa, PyObjC  
and, eventually, CamelBones (and whoever else wants to join the party).

Note that RubyCocoa fails in the same way.

Removing one of the stupid exception suppressors for the moment, the  
full exception barfed up is this:
