Reading bumper state from PR2

System: Ubuntu 10.10, kernel 2.6.35-27, 64 bit.
ROS: Latest diamondback from the repositories.

I'm following the PR2 tutorial here:
http://www.ros.org/wiki/pr2_simulator/Tutorials/BasicPR2Controls

Everything works fine, I'm mostly interested in the gripper and I can open and close it using rostopic.

What I can't do is read the state of the bumper: when I execute rostopic echo l_gripper_l_finger_bumper/state I get the following error message:

WARNING: no messages received and simulated time is active.
Is /clock being published?

Executing rostopic echo /clock indicates that the clock is indeed being published.

Has anyone else gotten the bumper plugin to work? Any hints/tips?
