In Tutorial:

After creating the urdf model as indicated and running the spawn command:

rosrun gazebo spawn_model -file `pwd`/object.urdf -urdf -z 1 -model my_object

I get an error message stating that cannot be opened (it is installed in my system). Here is the whole message:

Gazebo crashes regularly on my system, are you able to spawn other objects?

I cannot spawn other objects and I cannot launch any other world launch file. Only the empty world.
