Paraview Segfault when running this script [solved]

Hi there,

For some reason this script crashes my Paraview. I’m using version ParaView-5.9.0-RC4-MPI-Linux-Python3.8-64bit on ubuntu 20.04

import paraview.vtk as vtk
from paraview.simple import *

points = vtk.vtkPoints()
points.InsertPoint(0, 0, 0, 0)
points.InsertPoint(1, 1, 0, 0)
points.InsertPoint(2, 0, 1, 0)
points.InsertPoint(3, 0, 0, 1)
pdo = vtk.vtkPolyData()
pdo.Allocate(4, 4)

triangle = vtk.vtkPolygon()

tris = [[0,1,2], [0,2,3], [0,3,1], [1,3,2]]
for t in range(0, 4):
    for p in range(0, 3):
        triangle.GetPointIds().SetId(p, tris[t][p])
    pdo.InsertNextCell(triangle.GetCellType(), triangle.GetPointIds())

tp = TrivialProducer()

This code seems to work fine with pvpython, so I’m not sure what’s up.

Actually, trying it a couple more times it seems to have worked without segfaulting. A full system restart might have been the solution here, I’ll re open this if the issue surfaces again.
