rug commands lock up in autoyast initscripts with sigabrt errors

Autoyast is locking up 20 percent of the time when using the rug command.

ERROR:

process14646: Applications must not close shared connections - seedbus_connection_close() docs. This is a bug in the application.
  D-Bus not built with -rdynamic so unable to print a backtrace

Workaround:

an example Init-Script :
----------------------------------
 /sbin/init 3
  echo 'Registering to ZLM Server'
  rm /var/lib/zmd/services
  pkill -9 -x zmd
  /etc/init.d/novell-zmd start
  sleep 15
  /usr/bin/rug ping -a
  /usr/bin/rug set require-verified-certs false
  /usr/bin/rug sa  -f -t zenworks https://164.99.98.97
# -f option adds service unconditionally and does not allow it to fail eg.if server not responding or network is down.

  /usr/bin/rug ping -a
  sleep 5
  echo 'Finished Registration'
  /sbin/init 5
-----------------------------------

If above steps still does not address the issue and exception is seen then as
workaround, try to disable NeworkManager for zmd : kill/stop zmd , Rename the
/usr/lib/zmd/modules/Novell.Zenworks.Zmd.NetworkManager.dll Module file and
start zmd back.
