I've tried to reproduce this bug on devstack and got the folowing results:
1. launch VM:
    nova boot ... --nic net-id=my-net-id myserver
2. add fixed ip
    nova add-fixed-ip myserver my-net-id
3. associate 2 floating ips with  fixed ips
    nova add-floating-ip --fixed-address x.x.x.1 myserver y.y.y.y.1
    nova add-floating-ip --fixed-address x.x.x.2 myserver y.y.y.y.2

4. delete vm's port
   bash# neutron port-delete 1d31621f-bdb9-4745-97a6-8c49554297c1
   Deleted port: 1d31621f-bdb9-4745-97a6-8c49554297c1

So, it forks fine for now and I move it to invalid state.

If you still have this issue, please add your steps to reproduce here.

Title:
  multiple floating ip port delete

Status in OpenStack Neutron (virtual network service):
  Invalid

Bug description:
  RDO icehouse on rhel6.

  I have an instance that has multiple floating ip's assigned to it.
  when I went to delete it, the delete fails. digging into the logs, I
  get:

  If I pull off one of the floating ip's, the delete continues ok. The
  code needs to be updated to support deleting the neutron port when
  multiple floating ip's are assigned.
