roscore in a terminal

then again

$ rosbag play laser.bag[ INFO] [1331111093.757680745]: Opening laser.bag

Waiting 0.2 seconds after advertising topics... done.

If you wait for the rosbag to finish playing and exit it will no longer be published.

I would run rosbag in a separate terminal and pause it while you get rviz setup, or run rostopic list.
