[Bug 1506958] [NEW] TypeError: object.__new__(thread.lock) is not safe, use thread.lock.__new__()

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

When using /usr/bin/nova-api, running $ openstack  availability zone
list -> works fine.

If using the wsgi scripts, and running nova-api via e.g. uwsgi, the same
client command fails as following:

Looks like a dejavu of https://bugs.launchpad.net/python-novaclient/+bug/1123561 but I am not certain.

This is with liberty final release (or so i believe at the moment).
