Classname same as file/module name leads to inheritance issue

My code worked fine when it was all in one file. Now, I'm splitting up classes into different modules. The modules have been given the same name as the classes. Perhaps this is a problem, because MainPage is failing when it is loaded. Does it think that I'm trying to inherit from a module? Can module/class namespace collisions happen?

MainPage.py

import BaseHandler
from models import Item
from Utils import render

class MainPage(BaseHandler):
    def body(self, CSIN=None): #@UnusedVariable
        self.header('Store')
        items = Item.all().order('name').fetch(10)
        render('Views/table.html', self, {'items': items})
        self.footer()

BaseHandler.py

from google.appengine.ext import webapp
from google.appengine.api import users
from Utils import *

# Controller
class BaseHandler(webapp.RequestHandler):
     # ... continues ...
