When trying to create bulk IPv6 subnet from .json file on devstack( ubuntu server 16.04, latest openstack master version ), it throws an 500 internal server error.
This only happens, when trying to create bulk IPv6 subnets in slaac and dhcp stateless modes and there is already another subnet on that specific network.
It works fine with dhcp stateful.
There is also no problem when trying to do this with "openstack subnet create" or without bulk .json file.
Here are reproduction steps:
$ . ~/devstack/openrc admin
$ openstack network create n1

Confirmed reproducer on current devstack (and also that plain openstack subnet create command works with similar parameters)
