Can you supply a test case?  First of all, how does it raise an
exception?

If you have to kill it like that, it's surely a basic Emacs bug,
regardless of any python.el bugs.

That shouldn't be necessary.  I think there were several things broken
or not fixed in the one shipped with Emacs 22, and that one sounds
familiar.  Sorry I don't have a working version since I didn't keep up
with the incompatibilities introduced by Emacs 22.

http://www.loveshack.ukfsn.org/emacs/python-21.el behaves as I expect
-- providing a null completion list -- if emacs.complete raises an
exception.
