Most likely it's stuck in the

  (python-send-receive "import emacs; print '_emacs_out ()'")

in run-python.  This is supposed to send the above command to python and
than wait for Python to reply by outputting "_emacs_out ()\n".
The `emacs' package is in ..emacs/etc/emacs.py.
Can you take a look at the *python* buffer see if it says something useful.
Or else take a look at ..emacs/etc/emacs.py and try to figure out why it's
not working right.
