Root cause is this deprecation messages: https://github.com/openstack/python-novaclient/blob/master/novaclient/client.py#L784

Probably we shouldn't call warnings.warn() with translated messages.
This bug has been open about 3 years without any activity.
And I'm not sure this bug can be reproduced with current master branch.
So I'm going to move it to "Opinion / Wishlist", which is an easily-obtainable queue of older requests that have come on.
This bug can be reopened (set back to "New") if someone can reproduce this bug on master branch or decides to work on this.
