[Python-mode] xemacs Potential problem

[Eric S. Johansson]

I'm experimenting with the latest beta and try to figure out what's the right 
set of options for configure for production version and I got this error. Any ideas?

(1) (file-mode-spec/warning) Error in File mode specification: Malformed list:
