You have probably set PYTHONDOCS in one of your shell's dotfiles, and
it is not inherited by the XEmacs you start from outside the shell. 
You could try to:

 1) add (setenv "PYTHONDOCS" "/Users/bthom/Documents/Python-Docs-2.4.3")
    to your .xemacs/init.el
 2) create a ~/.MacOSX/environment.plist file; see 
 3) if you use SSHKeyChain, modify the environment using it
    (I think this just modifies the environment.plist file)

This happens to me if I run M-x shell in XEmacs and start up vi within
the shell. Funnily, it first complains about the terminal but then
starts up anyway. Somehow you'll have to tell ipython to use the same
XEmacs as the editor; hopefully someone on this list is more
knowledgeable about ipython.el than I am. (Perhaps just set the editor
to gnuclient?)

If it is indeed vi that starts up, try typing :q! and Enter.
