This occurred after the unicode conversion.
After an order is completed, it is not showing up in the pending section of the admin interface. The problem is that the code to show pending orders has some unicode subtleties.
/satchmo/shop/views/admin-portal.py lines 14 and 15 need to be modified to explicitly force the conversion.
The force_unicode function described here - http://code.djangoproject.com/browser/django/trunk/docs/unicode.txt
should fix it.
