Gazebo crashes at exit after using the transform tool

[azeey]

Environment

• OS Version: Ubuntu 18.04
• Source or binary build? Source (main, future Edifice)

Description

• Expected behavior: Gazebo does not crash
• Actual behavior: After using the transform tool to move an object and pressing play, exiting Gazebo via the gui or typingctrl-c on the terminal causes it to segfault. The segfault seems to only happen if the Component Inspector is enabled.

Steps to reproduce

1. ign gazebo shapes.sdf
2. Ensure that the Component Inspector is loaded
3. Using the transform tool, move the box object
4. Start simulation by pressing the play button
5. Exit gazebo

This appears to be fixed in my testing, so I'll go ahead and close.
