I don't like having too many entries in PATH.  ipython is the only
script that I use from that directory.

I tried starting xemacs -q which bypasses init.el.  Entering (require
`ipython) in *scratch* now gives the error about py-shell-map.  If
however I enter (setq ipython-command ...) first then all is well.

My guess is that you are doing a setq or similar before (require
`ipython) which is causing some py- stuff to load.  In my case I
suspect that customize is provoking the load, so ipython fails in
init.el as that is too early.  By the time I get to the *scratch*
buffer customize has done its thing.

I've now removed ipython-command from custom and moved it into
init.el.  The relevant part of that is now two lines.  Startup is now

(setq ipython-command "d:/Program Files/Python25/Scripts/ipython.bat")
(require `ipython)

Thank you.  XEmacs + IPython + pylab is a formidable combination.
