Hello all!

I updated my Gazebo version to 7.8.1 and ros-kinetic in Virtual Box with Ubuntu 16.04 but now I have a problem with turtlebot3 spawn model: The git source is here:

https://github.com/ROBOTIS-GIT/turtlebot3

https://github.com/ROBOTIS-GIT/turtlebot3_simulations

If you execute this command

roslaunch turtlebot3_gazebo turtlebot3_empty_world.launch

You can get such mistake:

Traceback (most recent call last):

The world is lunching but the robot model is absent. But before gazebo update I created my one world (in Gazebo 1.9) based on turtlebot3_empty_world and from saved copy I can launch the robot spawn model but I can't any world info like gazebo/model_states and gazebo/link_states .

I saw the same mistake here, but there was no answer there.
