Again, this happens during the *test discovery*. I'm not using Tox
(package maintainer never do). FYI, I'm simply doing:
python3 -m pytest tests/unit
If you know how to disable the errors on warning during test discovery,
let me know. But right now, this equals to FTBFS for rally-openstack in
Debian (the package was removed from testing because of it...).
