Comment 4 for bug 776555

Another work-around that should work with the correct code and the broken code:

  def start(self, filename, url, basename, *args, **kwargs):
    if len(args) >= 1:
      length = args[0]
      if len(args) >= 2:
        text = args[1]
      else:
        text = kwargs.get('text')
    else:
      length = kwargs.get('size') if kwargs.has_key('size') else kwargs.get('length')
      text = kwargs.get('text')
