Tully,

thanks for the hint! I did a svn up in joystick_drivers and there now
it is already added in the dep file :-)
And yes, that is not the problem causing the segfault.

Dejan,

finally found out how to debug the python program with gdb (removed
the node from the launch file and ran gdb python seperately).
here is the trace:

(gdb) run turtle_tf_listener.py __name:=turtle_listener
