Comment 4 for bug 939580

Alright so I'm not sure if this is the same issue at all, but here is my steps to recreate what my problem is.

1. Create instance
2. Assign floating ip from any pool
3. Delete instance from nova client or Dashboard
4. Try to access the Access & Security tab or do a nova floatin-ip-list
5. Get a " ERROR: The server has either erred or is incapable of performing the requested operation. (HTTP 500) "

To fix this I have to go into the database and disassociate the floating ip and fixed IP from the instance ID
