Discovered this while attempting to upload a new patch to ubuntuone-installer on quantal and having the tests fail with the following error:

dobey@u1-client-tarmac-trunk:~/ubuntuone-installer$ ./run-tests Traceback (most recent call last):

This same issue existed on the previous version as well, but in the exact opposite manner, though was not exposed in general, as gi.repository would have been tried first then, and so apps using it would have been fine.
