I can't reproduce this, here's my output:

I'm using OS X 10.6.6,  Python 2.6.1. May be a Python3 issue.

I have tested on Python 2.7.1 and works correctly.
It seems that this problem only occurs on Python 3.

email.message_from_bytes() function has been introduced in Python 3.2. Is it 
intentional that Python 3.1 is no longer supported?

(Personally I don't need to use Python 3.1.)
