Topic "/klt_points" killed the launched node "visp_auto_tracker" #103

Hi everyone,

I have a question regarding the visp_auto_tracker node. It works pretty well. However, when I tried to run rostopic echo /klt_points, it kills the launched file (i.e., roslaunch visp_auto_tracker tutorial.launch).

Any idea why this happened? BTW, this is not the case when I run roslaunch visp_tracker tutorial.launch

Many thanks in advance!

The goal of this node is to give the pose of the object on topic /visp_auto_tracker/object_position. KLT keypoints are used internally by the tracker. There is no reason to publish their coordinates. The topic /klt_point is listed but shouldn't.
