Not sure if my problem is similiar to [1], but this have been flagged as solved and I still have it in Fuerte.

I follow the tutorial "MappingFromLoggedData" at [2], and after I start "rosbag play ..." if I do a "rostopic hz /tf" there is no output.

The map gets generated correctly, so everthing else is fine!

Have you tried playing with rosbag play --clock?

rostopic hz requires a time component. If the 'use_sim_time' parameter is set to true, you need to publish the time using rosbag play --clock.
