I'm running Ubuntu 12.04 LTS x64 + OpenStack Havana with the following neutron package versions:

neutron-common 2013.2~rc3-0ubuntu1~cloud0
neutron-dhcp-agent 2013.2~rc3-0ubuntu1~cloud0
neutron-l3-agent 2013.2~rc3-0ubuntu1~cloud0
neutron-metadata-agent 2013.2~rc3-0ubuntu1~cloud0
neutron-plugin-linuxbridge 2013.2~rc3-0ubuntu1~cloud0
neutron-plugin-linuxbridge-agent 2013.2~rc3-0ubuntu1~cloud0
neutron-server 2013.2~rc3-0ubuntu1~cloud0
python-neutron 2013.2~rc3-0ubuntu1~cloud0
python-neutronclient 2.3.0-0ubuntu1~cloud0

When adding a router interface the following error message in /var/log/neutron/server.log:

I was not able to reproduce the issue.
Could you give a sequence of operations?

However from the trace the root cause and the fix seem obvious.

Importance should be high as it breaks routers.
