I'd very much like to get to the bottom of this - so please do stop by
and we'll sort it out. I imagine it has to do with a version difference
between what you have installed and what testrepository itself wants
(even though nova doesn't list a version of python-subunit, I believe
testrepository does. Yay for versioning!) Anyway - please drop by the
channel and we'll get you sorted.
