Hector quadrotor indoor tutorial simulation wont start

edit

I am trying to run the hector quad rotor indoor example from the tutorial ( http://wiki.ros.org/hector_quadrotor/... ). When I run it the rvis visualization and gazebo simulation open, but gazebo is blank and closes by itself. How can I fix it?

Below is the terminal output. There are two errors of which I don't know the meaning.

user@ubuntu:~$ roslaunch hector_quadrotor_demo indoor_slam_gazebo.launch
