Open Stack

Hi,

I installed openstack grizzly with nova-network, and A few days ago I
upgraded grizzly from 2013.1.4 to  2013.1.5.
After that, I have met a certain error,"*'LocalManager' object has no
attribute 'l3driver'", * whenever disassociating floating ip from
instance(click the button 'disassociate floating ip' on the dashboard)
Has anybody experienced that error ?

==================================================================
(in /var/log/nova/nova-api.log)
