Can't create network when ENABLE_TENANT_VLANS=True

Hi, when I try to create network under admin Project-Networks
I get an error

Failed to create network "test": 503-{u'NeutronError': {u'message': u'Unable to create the network. No tenant network is available for allocation.', u'type': u'NoNetworkAvailable', u'detail': u''}}

This happens only when I build devstack using
ENABLE_TENANT_VLANS=True

if I use instead the GRE tunnel
ENABLE_TENANT_TUNNELS=True

everything is fine.

I am using "Ubuntu 12.04" & "OpenvSwitch 1.11"

Here is my localrc:

disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service neutron
Q_PLUGIN=ml2
ENABLE_TENANT_VLANS=True

Here is the log from horizon_error.log:

I found that this bug was apparently fixed here
https://review.openstack.org/#/c/51994/

But why do I still get it?
I use
git clone https://github.com/openstack-dev/devstack.git

maybe it is not the latest?

Thanks,
Qshadow.
