gazebo fuerte crashes after calling gazebo/delete_model service
Hi I was following the simulator_gazebo tutorial on ROS wiki when I encountered this problem. First of all I spawned a model using " rosrun gazebo spawn_model -param coffee_cup_description -gazebo -model coffee_cup -x 0 -z 2 " and then I deleted it using " rosservice call gazebo/delete_model '{model_name: coffee_cup}' ". After I called the delete_model command,gazebo crashed unexpectedly and gave the following:
[gazebo_gui-3] process has died [pid 3162, exit code 139, cmd /opt/ros/fuerte/stacks/simulator_gazebo/gazebo/scripts/gui __name:=gazebo_gui __log:=/home/chengxiang/.ros/log/fba33798-f058-11e1-8139-0017c4794a79/gazebo_gui-3.log]. log file: /home/chengxiang/.ros/log/fba33798-f058-11e1-8139-0017c4794a79/gazebo_gui-3*.log
Other than this instance, gazebo also crashes unexpectedly sometimes when I was doing other stuffs like spawning models. Did any one of you encounter this issues before? Any advice will be appreciated. Thanks.
On a side note, my gazebo sometimes launches with a blackout screen, could this be related?
In addition, I am using Ubuntu 12.04.
