PyGIWarning: GnomeKeyring was imported without specifying a version first.

Importing the keyring module produces a warning:

    $ python
    Python 2.7.8 (default, Oct 20 2014, 15:05:19)
    [GCC 4.9.1] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import keyring
    /usr/lib/python2.7/dist-packages/keyring/backends/Gnome.py:6: PyGIWarning: GnomeKeyring was imported without specifying a version first. Use gi.require_version('GnomeKeyring', '1.0') before import to ensure that the right version gets loaded.
      from gi.repository import GnomeKeyring

The GNOME backend ought to use gi.require_version(...) to suppress it.
