pvpython startup crash (5.5.2, Arch Linux)

On startup of pvpython it crashes immediately after the update to 5.5.2.
Additionally, my python plugins crash with a similar segmentation fault now.

This problem is likely caused by a regression in Python 3.7. See the discussion at https://gitlab.kitware.com/vtk/vtk/issues/17363. Changing to PYthon 3.7.1 should resolve the crash.

Hi Cory,

Thanks for getting back to me, indeed with Python 3.7.1 I do not experience this crash anymore (paraview 5.6.0 on arch linux)

Best,
Daan
