This is the commit that I reverted and was able to get rid of the error:

    Allow users to run 'tox -epy34'

    With this commit, it is possible to successfully run 'tox -epy34', even though
    only a small amount of tests will actually be run. This is a required step in
    making Neutron compatible with Python 3, as described in the 'Porting to Python
    3' specification.

    This commit:
    - fixes some broken imports, while making sure they still work with Python 3;
    - updates a call to gettext.install;
    - adds a py34 target in tox.ini.
