I'm calling the mail-gateway with outdated locale .po files in the local
instance (I have an instance with its own locale directory) and I'm
getting the attached traceback.

Note that when I go back to 2d6a92c3e212 (before the python3 changes to
i18n.py) compilation of the locale files works fine. I don't see any
obvious changes that would explain the traceback to i18n.py, though.

Note that I'm getting this error with python2.7 not python3
