I did check the output of view_frames and there is only ONE tree, also
the TF-display of rviz display the tree correctly.

No, I am not running in simulation but on the real robot (a P3AT).
The most strange thing is - in my opinion - that I can get the correct
transformation with tf_echo while my code is throwing this error.
