[ros-users] cturtle's Gazebo Crashing with Ogre error

[Patrick Beeson]

If I encounter this again, I'll try this solution.  But as of now, after 
running as root, and now even after reboot, it simply works.  Maybe 
there was an issue with shared memory that needed a reboot or root 
permissions to fix.
