Cannot launch PR2 navigation under Hydro-simulation [closed]

edit

Hi,

when trying to run the PR2 navigation under Hydro the laser_filters die always. It's namely the scan_to_cloud_filter_chain node form the laser_filters 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:
