Comment 4 for bug 872835

Same as bug 844934:

Gazebo crashes with this version on the trunk : http://answers.ros.org/question/2184/getting-my-custom-transmissions-to-work-in-gazebo

To solve this problem, you need to comment out publishMechanismstatistics() in pr2_controller_manager/src/controller_manager.cpp and recompile the pr2_controller_manager... I'm still waiting for an answer on why this is not working :S

Hope this helps.
