Bug#1010027: python3-paraview: pvpython does not run scripts

[Giuseppe Bilotta]

Package: python3-paraview
Version: 5.10.1-2+b1
Followup-For: Bug #1010027

The bug is still present in 5.10.1-2+b1, and it affects both pvpython
and (arguably even worse) pvbatch. It seems that the command-line
options are never even read, even putting in a bogus file name like:

    pvbatch nonexistent.py

(with no actual nonexistent.py file present) has no effect.
This is in contrast e.g. with 5.9.0 that (as expected) errored out with:

    /usr/bin/../lib/x86_64-linux-gnu/vtkpython: can't open file '/xxxx/xxxxx/nonexistent.py': [Errno 2] No such file or directory

One thing of note is that in the working 5.9 installation, pvpython ends
up delegating to vtkpython. Running strace on the broken 5.10 reveals
pvpython trying to access vtkpython and failing

    readlink("/usr/bin/../lib/x86_64-linux-gnu/vtkpython", 0x7fffe0794790, 4096) = -1 ENOENT (No such file or directory)

and then falling back to the standard python interpreter. I suspect this
may be related to the issue.
