Initial Comment:
Noticed this due to an Ubuntu build failure:

Fails with current GIT head too

Message:
This is now fixed in git. 

Actually, I think this was caused by a bug in the python library; at least
it is an incompatible change in python 2.7. See commit f6046b9 in the
archivemail git repo for details. 

Thanks for reporting.
