How about using "globals()" instead of trying to get access to the 
module.

def processUpload(filename, directory):
   "Process the user-uploaded files"

   def getFileHandler(filename):
     "Return the file handler class according to the file extension"

     subclass = "%sFileHandler" % 
os.path.splitext(filename)[1].upper()[1:]
     return globals().get(subclass,FileHandler)

   getFileHandler(filename)(filename, directory)

Think I worked out what you were trying to do.
