I can confirm the bug - and it gets reproduced easily with the steps mentioned.
However, the problem seems to be in the horizon code and doesn't seem to be in neutron. Also all the logs you have pasted, doesn't seem to be relevant.

In the dashboard/api/lbass.py file:

def _vip_get(request, vip_id, expand_resource=False):
    vip = neutronclient(request).show_vip(vip_id).get('vip')
    if expand_resource:
        vip['subnet'] = neutron.subnet_get(request, vip['subnet_id'])

The subnet get is what fails in this case but there seems to be no handler for that.
The error is correctly reported in the neutron server log as well:

show failed (client error): Subnet e898cfa9-87ab-481c-8ecd-79c0f1af2894
could not be found

As far as the lbaas warning is concerned - that sounds a bit legit:

    def get_stats(self, pool_id):
        socket_path = self._get_state_file_path(pool_id, 'sock', False)
        TYPE_BACKEND_REQUEST = 2
        TYPE_SERVER_REQUEST = 4
        if os.path.exists(socket_path):
            parsed_stats = self._get_stats_from_socket(
                socket_path,
                entity_type=TYPE_BACKEND_REQUEST | TYPE_SERVER_REQUEST)
            pool_stats = self._get_backend_stats(parsed_stats)
            pool_stats['members'] = self._get_servers_stats(parsed_stats)
            return pool_stats
        else:
            LOG.warn(_('Stats socket not found for pool %s'), pool_id)
            return {}
