I had the same problem. The crux was that there was obviously and old version of virtinst still half-installed after the upgrade from hardy. The file /usr/lib/python2.6/dist-packages/virtinst-0.300.2.egg-info for example was present on my system. I solved the problem as follows:

# Will remove ubuntu-virt-mgmt and virt-manager as well
sudo aptitude purge virtinst
sudo rm /usr/lib/python2.6/dist-packages/virtinst-0.300.2.egg-info
sudo rm -Rf /usr/lib/python2.4/dist-packages/virtinst*
sudo rm -Rf /usr/lib/python2.5/dist-packages/virtinst*
sudo rm -Rf /usr/lib/python2.6/dist-packages/virtinst*
# Will re-install virt-manager as well
sudo aptitude install ubuntu-virt-mgmt

Seems to be a bug in python-support.
