I haven't reproduced the failure but the same problem exists with software-center (bug 905605) and software-properties-gtk (bug 905602)
This is caused by the following change in pygobject
http://git.gnome.org/browse/pygobject/commit/gi/overrides/Gtk.py?id=654711d0f940d7480d0f1cdb25a3dc9996f7a706

** Changed in: ubiquity (Ubuntu Precise)
   Importance: Undecided => High
