Oh, I can reproduce the error without globals too.
Here:
from sqlalchemy.dialects import mysql
def render_item(type_, obj, autogen_context):
print "This is a global:", mysql
from sqlalchemy.dialects import mysql as mysql2
print "This is not a global:", mysql2
Output:
This is a global: None
This is not a global: <module 'sqlalchemy.dialects.mysql' from
'/home/fayaz/Programming/weaver-env/local/lib/python2.7/site-packages/sqlalchemy/dialects/mysql/__init__.pyc'>
