Looks like the code is assuming that router_ids can never be None, which clearly is the case here. Is that a bug?<br>
<br>
Looking elsewhere in the l3_db.py, L3RpcNotifierMixin.notify_routers_updated() does make a check for router_ids (which means that that function does expect it to be empty some times), but the list() is killing it before it reaches that.<br>
<br>
This backtrace repeats itself many many times in the neutron logs.<br>

Thanks for your help.<br>
