I'm following the Turtlebot tutorial here: http://www.ros.org/wiki/Robots/TurtleBot. I'm trying to launch the dashboard, but it doesn't work and I get the output below. However, I am able to teleoperate my robot with the keyboard so the connection is functional. How can I fix this? I'm using Fuerte and my environment vars have been set as in the tutorial.

 $ roslaunch turtlebot_dashboard turtlebot_dashboard.launch
