Since it's really a python bug, I'd rather see it fixed upstream than adding 
(yet another) hack in ipython to defend against it.  But I also don't want 
ipython to crash for users, that's for sure.

Let's see if John can get his pycxx animals to grow a __repr__, which will fix 
the issue.  If that doesn't work, I'll go ahead and stick in a 
version-specific defense layer into Prompts.py to at least help the ipython 
users, while python fixes the problem upstream.

Cheers,
