Turtlebot simulation crashes when launched

edit

I have installed the software like it is said in the page.

my system info is:

• ubuntu 12.04
• ros hydro
• gazebo 1.9

However when i try to run it:

roslaunch turtlebot_gazebo turtlebot_empty_world.launch

gazebo crashes when he should spawn the bot. The log message i get when this happens is:

Dbg Plugin model name: mobile_base [spawn_turtlebot_model-4] process has finished cleanly log file: /home/samper/.ros/log/e4873b52-135d-11e4-bbd0-109add68f52e/spawn_turtlebot_model-4.log Segmentation fault (core dumped) [gazebo_gui-3] process has died [pid 25180, exit code 139, cmd /opt/ros/hydro/lib/gazebo_ros/gzclient __name:=gazebo_gui __log:=/home/samper/.ros/log/e4873b52-135d-11e4-bbd0-109add68f52e/gazebo_gui-3.log]. log file: /home/samper/.ros/log/e4873b52-135d-11e4-bbd0-109add68f52e/gazebo_gui-3.log

I don't know why it is happening, other urdf models like shadow hand and arm are working pretty nice.

------------- EDIT -------------

when i check the log files i get this information:
