I see that nova havana changed from six < 1.4.0
to six >= 1.4.1

So I suspect you have conflicting versions between various components?
Maybe some older client is being loaded by nova which
is then enforcing the older six version check,
so upgrading your clients might help?

I presume you're not using a packaged OpenStack distribution, but
for what it's worth you can correlate with the latest (client) versions here:
http://rdo.fedorapeople.org/openstack-havana/epel-6/
(that repo implicitly pulls in six-1.4.1 BTW).
