[Paraview] ImageReader fails with pvbatch: MPI_Type_create_subarray(124): Argument array_of_starts has value 4 but must be within [0, 0] on 3.12, 3.98 linux

[Anton Shterenlikht]

I've isolated the problem to this small script:

from paraview.simple import *

reader=ImageReader(FilePrefix= "z9end.raw" )
reader.DataByteOrder=1
reader.DataExtent=[1,80,1,80,1,640]
reader.DataScalarType=5

view = GetRenderView()
Show()

It works with:

- 3.10 pvbatch on FreeBSD
- 3.10 pvpython on FreeBSD
- 3.12 pvpython on linux
- 3.98 pvpython on linux

It fails with:

- 3.98 pvbatch on linux
- 3.12 pvbatch on linux

3.98 error:
