Public bug reported:

Ubuntu 12.04.04 / OpenStack Havana (RPC 4.2.2)

Setting a boolean of the wrong case in /etc/openstack-
dashboard/local_settings.py causes 500s.

I inadvertently set 'enable_lb': true (lowercase true):

# The OPENSTACK_NEUTRON_NETWORK settings can be used to enable optional
# services provided by neutron. Options currenly available are load
# balancer service, security groups, quotas, VPN service.
OPENSTACK_NEUTRON_NETWORK = {
    'enable_lb': true,
    'enable_firewall': False,
    'enable_quotas': True,
    'enable_vpn': False,
    # The profile_support option is used to detect if an external router can be
    # configured via the dashboard. When using specific plugins the
    # profile_support can be turned on if needed.
    'profile_support': None,
    #'profile_support': 'cisco',
}

Changing it to "True" fixed the issue.

I'm all for consistency and details - but seems a bit too strict and
could cause unnecessary troubleshooting.
