Delete Model Not Working

[hboortz]

The "Delete Model" command is not working from this tutorial: http://gazebosim.org/wiki/Tutorials/1.9/ROS_Communication_with_Gazebo .

When you run

rosservice call gazebo/delete_model '{model_name: rrbot1}'

And rrbot1 does exist, a segfault occurs:

DEBUG ros.gazebo_ros: Waiting for model deletion (rrbot)
Segmentation fault (core dumped)
/home/dave/ros/ws_gazebo/src/gazebo_ros_pkgs/gazebo_ros/scripts/gazebo: 25: kill: invalid signal number or name: SIGINT

I have confirmed this issue.

[hsu]

For me gzserver continues to run, but gzclient crashes with following backtrace:

Program received signal SIGSEGV, Segmentation fault.
