/usr/bin/glade2script:4800: PyGIWarning: Notify was imported without specifying a version first. Use gi.require_version('Notify', '0.7') before import to ensure that the right version gets loaded.
  from gi.repository import Notify
/usr/bin/glade2script:4804: PyGIWarning: AppIndicator3 was imported without specifying a version first. Use gi.require_version('AppIndicator3', '0.1') before import to ensure that the right version gets loaded.
  from gi.repository import AppIndicator3 as appindicator

I installed a fresh one ubuntu 17.04, gnome version and after all updates, i installed grub-repair. I got this error at first run:
     gi.require_version('AppIndicator3', '0.1')
  File "/usr/lib/python2.7/dist-packages/gi/__init__.py", line 118, in require_version
    raise ValueError('Namespace %s not available' % namespace)
ValueError: Namespace AppIndicator3 not available

Fixed in the PPA
(glade2script - 3.2.3~ppa1)

thx Fred for the ticket

"ImportError: No module named gi" error should be fixed,
but some "... was imported without specifying a version first" warnings may still appear, without consequence AFAIK.
