It should work if you run gazebo from within the /usr/share/gazebo-1.8/worlds folder.

The issue is that grass.world is referring a the my_mesh.dae resource, but Gazebo can't find that resource. You could also specify a complete file URI for the mesh:

<mesh><uri>file:///usr/share/gazebo-1.8/worlds/my_mesh.dae</uri></mesh>
