Bug#837796: paraview: segfaults when performing query-based selections

[Drew Parsons]

Package: paraview
Followup-For: Bug #837796
Control: fixed -1 5.11.0+dfsg-1

I think this problem is now dealt with (paraview 5.11).

The query-based selection is not segfaulting now.  The values are
found as described in the tutorial, and the 3D can image gets
highlighting indicated the selection points.

There is a warning message if python3-paraview is not installed,
though the selection nevertheless proceeds without segfault.
Selection proceeds cleanly if python3-paraview is installed.
