Am trying to get pose, velocity and acceleration data of an object given by the vicon system. Am using the package of vrpn_client_ros . Echoing the pos and velocity works good but the node crashes when I try to echo the topic that publish the acceleration and here is the error I get:

Any help would be appreciated. thanks
