@Seth, I'm surprised the 3D viewer doesn't crash when there is no openGL. AFAIK, the 3D viewer requires opengl for rendering and does not use cairo or any other device context. Is there some way to disable the ray tracing if opengl is missing?

I should have been more clear. It doesn't do the OpenGL version check. So rendering works with some artifacts (depending on what's available) but raytracing requires something that is not available.

We could utilize the OpenGL check before launching the 3d-viewer. That will catch most issues.

summary: - 3d-viewer segfaults when raytracing if OpenGL is not available
+ 3d-viewer segfaults when raytracing if OpenGL 2.1 is not available

It should be enough to just disable the ray tracing button when opengl isn't new enough to support it.

@Seth, I finally found some time to take a look at this. I don't have a version of OpenGL to test this but I simulated by changing the minimum OpenGL version to something higher than the version I am using. Please test this on whatever platform you used to generate this bug report when you get a chance so I can get this fixed for 5.1.

Orson/Janitor you forgot to set this bug as fix committed
