I have noticed that sometimes a form key name can be none. Not sure
if this was a mod_python 2.7.X specific thing or not, but my forms
code has:

      # Some strange forms can result in fields where the
      # key value is None. Wipe this out just in case this
      # happens as can cause problems later.

      if args.has_key(None):
        del args[None]

You may therefore simply want to ignore case where q.name is None.
