I looked at the traceback in more detail, and as far as I can see, all of the 
calls causing the exception are in the pydoc.py code, triggered by the 
original help __call__() in site.py.  This is all code from the python 
standard library, not in ipython itself.  So I'm starting to wonder if somehow 
ipython's use of the help() facilities in python is triggering a bug in python 
2.3.  I know that pydoc has changed significantly in 2.3, because I got 
another seprate problem report related to pydoc which doesn't occur in 2.2.

I normally work in 2.2 and my laptop doesn't have 2.3 (though my office 
machine does), so I hadn't noticed any of this myself.

Note that I'm not saying necessarily that it's a python bug for certain, all I 
know is that ipython may be interacting with 2.3's pydoc in ways which are 
invalid, but which used to work with 2.2.

Huh?  Exactly who do you accuse me of insulting?  I simply stated a fact: for 
me it's difficult to provide good support for Windows users, because I don't 
use the platform myself, and often Windows-related problems go unsolved.  I 
regret it, but it's a reality.
