rviz: crash when mousing over a marker when it is deleted

[Saki-Chen]

You can try the python script below to generate a rectangle in rviz.
When you enable focus and move the cursor to it, rviz will crash with Segmentation fault.

OS: Ubuntu 18.04
ROS Distro: Melodic

[rhaschke]

I can confirm this bug using the nvidia driver, but not using the Mesa driver. Below is the backtrace. Unfortunately, there is no maintainer left, which can further debug or analyze this issue. Any help is welcome. I'm (again) suspecting the shader scripts in ogre-media/materials/*150. The segfault occurs for both, GLSL 1.2 and 1.5.
