Foreman » Smart Proxy

After upgrading from foreman-proxy version 1.9.3-1 to 1.10 (I just tested on 1.10.2)
I started seeing this error , when I go to: http://myserver.....net:8443/dhcp
I see:

undefined method `sort' for nil:NilClass

Everything else works fine. Foreman can get new IPs. I just cannot connect to the web interface.

If I rollback to the old version everything is OK, I just do:

yum erase foreman-release foreman-proxy
yum clean all

install version 1.9

yum localinstall http://yum.theforeman.org/releases/1.9/el6/x86_64/foreman-release.rpm
yum install foreman-proxy
mv settings.yml.rpmsave settings.yml
mv settings.d/dhcp.yml.rpmsave settings.d/dhcp.yml
service foreman-proxy restart

and everything back to normal.

Foreman-proxy settings:

# cat settings.yml 
--- 
#replace default location of "settings.d" 
:settings_directory: /etc/foreman-proxy/settings.d

:daemon: true
:http_port: 8443
:daemon_pid: /var/run/foreman-proxy/foreman-proxy.pid
:log_file: /var/log/foreman-proxy/proxy.log
#:log_level: INFO
:log_level: debug

here is the foreman-proxy log:
