You mean you don't have any star imports in the module causing error?

Run your script from the command line (not your editor). Then give the 
complete traceback.

Grep through the libraries you use for 'from locale' and 'import locale' to 
identify the one that uses the locale module. You can identify modules used 
by your script by running

python -v script.py

Aside: if you use a version control system and check in frequently it gets 
easier to identify a modification that introduced an error. Highly 
recommended.
