Hi,

when trying to run the PR2 navigation under Hydro the laserfilters die always. It's namely the scantocloudfilterchain node form the laserfilters package. To reproduce, do the following under Hydro:

roslaunch pr2_gazebo pr2_empty_world.launch
rosrun map_server map_server <a map>
roslaunch pr2_2dnav pr2_2dnav.launch

The latter leads to the following error:
