Comment 1 for bug 734050

I've met this before running a quickly app outside ubuntu. What worked for me was to replace

from gi.repository import GObject # pylint: disable=E0611

with

try:
    from gi.repository import GObject # pylint: disable=E0611
except ImportError:
    import gobject as GObject

I don't have Natty so cannot test this in your environment. Can you try this and give us some feedback. patch attached
