moveit_setup_assistant exit code -11

edit

Hi! I try load URDF from sw_urdf_exporter to MoveIt. Path is:

/home/tuuzdu/Hexapod/Leg/robots/Leg.urdf

I add this path to ROS_PACKAGE_PATH:

export ROS_PACKAGE_PATH=/opt/ros/hydro/share:/opt/ros/hydro/stacks:/home/tuuzdu/Hexapod

Then I load Leg.urdf to moveit_setup_assistant and get:

[ INFO] [1383333621.031734075]: Loaded Leg robot model.
