This error is showed with the default Quickly application template on Ubuntu 12.04 and according to https://bugs.launchpad.net/pygobject/+bug/974729/comments/2 it can be fixed in /usr/lib/python2.7/dist-packages/gi/overrides/Gtk.py which belongs to the python-gi package which has pygobject as a source.
You need to give some more information about how to reproduce this. Please attach some example code which generates this error, or describe how to run the code you are running. https://launchpad.net/ubuntu-accomplishments does not show a PPA nor a branch, "bzr branch lp:ubuntu-accomplishments" does not work, and the package is not in Ubuntu Quantal.
Commands to reproduce on the current Ubuntu 12.04 installation: sudo apt-get install quickly quickly create ubuntu-application test cd test/ quickly run
Created attachment 217190 [details] reproducer Thanks. Attaching standalone reproducer. This happens when reading a subclassed Gtk.Window from a Gtk.Builder.
Fixed in master with a rather extensive test case.
