Comment 3 for bug 1363637

The fix is here: http://cgit.freedesktop.org/gstreamer/gst-python/commit/?id=4c08c3396c3cdadc939a9889f1e4664f938921a0

The problem was introduced in PyGobject in that particular commit: https://git.gnome.org/browse/pygobject/commit/?id=3a2bfc8bf01fcae386355bc3652780e198e54d49

Please at least add that patch in gst-python so that pitivi can be used with default packages on ubuntu.
