TypeError: __init__() takes exactly 4 arguments (5 given)

when running "rubber -m dvipdfm test.tex" I got this error:

Traceback (most recent call last):

    sys.exit(Main()(sys.argv[1:]))

It seems in depended of the TeX file to process. Doing things manual (latex…, dvipdfmx ….) works fine. What does the error mean? What to do?

I'm using Ubuntu 13.10 Saucy Salamander and Rubber version: 1.1
