launching gazebo fails with ros-groovy-pr2-interactive-manipulation

Hi,

I've just installed ROS groovy on the last Ubuntu LTS and I'm trying to run manipulation samples with PR2 (sorry I'm not authorized to add a real link but here it is: wiki.ros.org/pr2_tabletop_manipulation_apps).

I start roscore, then launch

roslaunch manipulation_worlds pr2_table_object.launch

Which generates an error:

Note: concerning the ros::InvalidNameException I replaced the invalid character by a #, but the original character is represented as the 0018 code.

Could you help me with that? The logs gazebo_gui-1 and 2 do not exist. I assume the crash is link with the exception above but I can't find any help or clue anywhere. I've recursively greped "gazeboeb" in my ROS package root but there are no result.

(I'm new to ROS :) Thanks
