Associating a floating IP address to a server through Horizon failed

[xiewj]

In Mitaka,
Associating a floating IP address to a server through Horizon failed

The error info Horizon retruned is as follows:
"Error: Request Failed: internal server error while processing your request. Neutron server returns request_ids: ['req-5519568b-3717-4907-a8c0-618503a538cc']"
Error: Unable to associate IP address 203.0.112.11.

Associating a floating IP address to a server through the 'nova floating-ip-associate <server> <address>' succeeded.

The neutron-server thrown an exception,it seems that the arguments Horizon passed is fewer than needed.

I'm not sure if there is also a problem with Horizon, but clearly there's a typo in the message string:

msg = (_('Floating IP %(floatingip_id)s is associated '
         'with non-IPv4 address %s(internal_ip)s and '
         'therefore cannot be bound.') % data)

%s(internal_ip)s is bogus - I'll send a patch
