Comment 2 for bug 1361708

Disassociate code calls the following

api.network.tenant_floating_ip_list(request) which has 500 error , tried it at the command line, it has the same issue as in UI.

....I did test using nova network

stack@gloria-stack:~/devstack$ nova floating-ip-list
ERROR (ClientException): The server has either erred or is incapable of performing the requested operation. (HTTP 500) (Request-ID: req-fcbbaf79-56b8-49b2-95b3-e381f4c0a214)
stack@gloria-stack:~/devstack$

once it calls floating_ip_list, then it seems to having problem all the time..
