[PyQt] glGetFloatv crashes application

So I'm trying to build a PyQt5 app. It's a tool to display a 3D
structure using OpenGL with some buttons and checkboxes to change view
and what is shown.
I'm currently having problem with glGetFloatv. The app crashes without
any error message everytime it is called.
I call it like this:
The reason I need to use it is that I have a problem with loading a
transformation matrix: it seems to work, but the transformation is
broken, even with the identity matrix. So I wanted to see what the
current matrix looked like using glGetFloatv.
If the status of OpenGL in PyQt5 is a bit buggy, is there anyway to use
PyOpenGL with PyQt5 instead?
Another problem I'm having is that whenever there is an uncaught
exception, the exception message is printed as usual, but the app also
crashes ("python3 stopped unexpectedly"). This is not OpenGL related.
I'm testing on MacOS Sierra (could not get OpenGL+PyQt5 to work on Linux
at all). PyQt5 version 5.7.1 installed with Homebrew. Python 3.6.0, also
installed with Homebrew.
