both v0.9.0 and master segfault

mayo is built from source on Alpine Linux Edge. When a step file is loaded it first throws what appears to be a QT error:
Error: OpenGl_Context is unable to wrap OpenGL context
Then segfaults when the model is clicked on to display.
under GDB:
[LWP 29151 exited]

Thread 1 "mayo" received signal SIGSEGV, Segmentation fault.

Hello @rickyrockrat
Try to set option "Force OpenGL Fallback Widget" to ON in the Tools->Options dialog:

Then restart Mayo application
