RViz quietly ignores if .rviz file given with -d option doesn't exist?
e.g. in Hydro,
$ rosrun rviz rviz -d $(rospack find urdf_tutorial)/urdf.rviz
$ rosrun rviz rviz -d $(rospack find urdf_tutorial)/urdf_noexist.rviz
With first line loads RobotModel pane for instance. With second line no error output printed, RViz
looks like starts with default config.
