Hi all，
While I'm cherry-picking havana stable 2013.2.4(nova) commits to our private branch， I found that this backport commit 97028309ff7a13ea5e9b8cc353d56ec9678caaff causes a pylint failure: nova/api/openstack/compute/contrib/floating_ips.py:203: [E1101, FloatingIPController.delete] Module 'nova.exception' has no 'Forbidden' member.
Then I downloaded the tar package on launched(https://launchpad.net/nova/havana/2013.2.4/+download/nova-2013.2.4.tar.gz), I checked the nova/exception.py, there is no 'Forbidden' class or other member in it, so I guess this is a mis-denpendency backport commit, this denpended commit c75a15a48981628e77d4178476c121693a656814 should be backported.
