[issue11116] mailbox and email errors

[Steffen Daode Nurpmeso]

New submission from Steffen Daode Nurpmeso <sdaoden at googlemail.com>:

Following Issue 9124 discussion: it took longer than i thought, but now i could rework my thing and got errors.  I've also tried Lib/test/test_mailbox.py, and that produces 0xA errors and 0xA failures.  I'll attach the entire tracebacks and test output as email_mbox.txt.
My local Py3K repo is at changeset HG:33774ca03c96 (SVN:r88332)
Here are only the exceptions:

==========
