Thank you very much for this. Indeed this fixed the problem.

Hi,

I am having a hard time running the turtlebot simulator with ros-fuerte on Ubuntu precise 12.04. I used to run the simulator without any problems with Ubuntu Lucid and ros-electric. It seems to be an issue with the gazebo server and the boost libraries. More specifically, after issuing:

roslaunch turtlebot_gazebo turtlebot_empty_world.launch

I get the following error:

waiting for service spawn_urdf_model gzserver: /usr/include/boost/smart_ptr/shared_ptr.hpp:418: T* boost::shared_ptr<t>::operator->() const [with T = urdf::Inertial]: Assertion `px != 0' failed.

Service call failed: transport error completing service call: unable to receive data from sender, check sender's logs for details

Aborted (core dumped)

I have observed the same behavior on 3 different 12.04 machines (Ububtu, lubuntu, Xubuntu). Is this a known problem for fuerte-precise turtlebot simulator or am I doing sth wrong? Note that stripping down the turtlebot urdf to just the create base seems to work - but that's definitely not a solution.
