[rdo-list] Langage env bug in ovs neutron agent for openvswitch

Hi, with newton, manually installed, when I start the neutron agent for openvswitch (on network node and/or compute nodes), the service fails, only saying "uncaught exception". We spent weeks to diagnos this problem. yes weeks... If I override LANG to C in systemd unit files it works !!! Seems a subcommand in some python librairies is waiting for "Exit code" in stdout, but on my system we have "Code de sortie" instead (french here). Is that a known bug ? Best regards, Edouard
