All that is saying is that your ROS node seg faulted somewhere, which is pretty much impossible to debug. Some guidelines on how to help the list help you: <a href="http://www.ros.org/wiki/Support#Guidelines_for_mailing_list_messages">http://www.ros.org/wiki/Support#Guidelines_for_mailing_list_messages</a></div>

Can you post the launch files and parameters that are causing the crash?</div>
