Hi all,

my Ros is Hydro and version of my gazebo is 1.9.1, when i run my huskey model with this command

roslaunch husky_gazebo husky_empty_world.launch

i got following error :

    [gazebo-4] process has died [pid 17134, exit code 139, cmd /opt/ros/hydro/lib/gazebo_ros`/gzserver worlds/empty.world __name:=gazebo __log:=/home/vahid/.ros/log/5a32d28e-3e12-11e3-9be5-78dd08cb9f84/gazebo-4.log].`
log file: /home/vahid/.ros/log/5a32d28e-3e12-11e3-9be5-78dd08cb9f84/gazebo-4*.log

any one knows what is the problem?! Thank you.
