[Paraview] Problem importing vtk inside pvpython

[Sebastien Jourdain]

I think you have VTK installed on your system which conflict with your
ParaView one. Hence the segfault inside ParaView.

Otherwise nothing should prevent you from doing pure VTK code in ParaView
as long as you are aware of the possible issue when running remotely and/or
in parallel.
