I use ubuntu 14.04, ros indigo, verion 1.11.9.
I run this command:
`roslaunch turtlebot_gazebo turtlebot_world.launch`
Sometimes I have a segmentation fault (core dumped). Then I try to rerun the command. It can work as usual or fail again. Usually after three or four rerun it works correctly. You can see the error below (or on the picture [2.png](/upfiles/14525311548846028.png)). I have no idea how to repeat this bug, but it appears quite often. Do you have any ideas how can I fix this problem?
I’ve seen some questions about segmentation fault but there was no answer which can help.
