[Dev] Connmanctl configuration issues from command line

We have an issue related to connman package v1.18, when trying to setup a network configuration on a fresh installed Tizen image:

WIRED_SERVICE=`connmanctl services | grep Wired | awk -F' ' '{ print $3 }'` ;  (actually WIRED_SERVICE becomes something like 'ethernet_1867b0236128_cable')
connmanctl config $WIRED_SERVICE --ipv4 manual --nameservers --proxy auto http://proxy/autoconfig.dat

The behavior of this command is completely non-deterministic, sometimes the proxy variable is set, but the network is not configured, sometimes the nameservers are missing, etc ...
At the same time, in the error log we can see error messages (such as core dumped connmanctl ...) after running the connmanctl command with any parameters.

Question: do we miss something in trying to setup a network configuration by using the connmanctl command with the given parameters?
We know that some bugs were submitted related to this strange behavior, but that happened back in connman v1.15, and now we're running the latest version (v1.18).

By default the connman service is active (running) after the first setup configuration:

connman.service - Connection service
   Loaded: loaded (/usr/lib/systemd/system/connman.service; disabled)
   Active: active (running) since Fri 2013-10-04
Main PID: 3491 (connmand)
   CGroup: name=systemd:/system/connman.service
           └─3491 /usr/sbin/connmand -n
