Hmm... it looks like the answer is here: http://answers.ros.org/question/88086
You simply run:
$ cd ~/catkin_ws/ then
$ catkin_make then
$ source devel/setup.bash
then you will get the right reply.
$ rosmsg show tf/tfMessage
geometry_msgs/TransformStamped[] transforms
std_msgs/Header header
uint32 seq
time stamp
string frame_id
string child_frame_id
geometry_msgs/Transform transform
geometry_msgs/Vector3 translation
float64 x
float64 y
float64 z
geometry_msgs/Quaternion rotation
float64 x
float64 y
float64 z
float64 w
you should append msgname
