Comment 4 for bug 870405

Dave,
  I hit this when trying to use an ubuntu git branch as the source of the nova component for devstack.
  Because of this bug, i wasted time figuring out what was going wrong, rather than spending that time figuring out whether or not an issue with trunk applied to Ubuntu. It is probably sufficient to have this fixed in 'P', as there will no doubt be other issues using devstack against a diablo release (as devstack will concentrate on functioning with trunk I would guess).
