Segfault while using planner.planPath(points)

Continuing the work from this issue: https://github.com/ros-industrial-consortium/descartes/issues/185

when I additionally uncomment from the tutoarial code

 // 3. Create a planner and initialize it with our robot model
  descartes_planner::DensePlanner planner;
  planner.initialize(model);

  // 4. Feed the trajectory to the planner
  if (!planner.planPath(points))
  {
    ROS_ERROR("Could not solve for a valid path");
    return -2;
  }

and have gazebo and moveit running (so urdf and srdl are present), I'll get the following error:

rosrun descartes_tutorials tutorial1

Aborted (core dumped)

Could you please include useful checks (to prevent segfaults) and issue some error messages to enable better debugging?

BTW: I am using Ubuntu 14.04 and Indigo

Thank you! Jan
