ubuntu-bug shows PyGI warnings

[Seth Arnold]

$ ubuntu-bug apport
/usr/share/apport/apport-gtk:16: PyGIWarning: Wnck was imported without specifying a version first. Use gi.require_version('Wnck', '3.0') before import to ensure that the right version gets loaded.
  from gi.repository import GLib, Wnck, GdkX11, Gdk

It doesn't appear to be harmful but it is ugly.

Thanks
