[Paraview] Why is pvbatch displaying images?

[Pradeep Jha]

I installed PV with OSMesa on a linux supercomputer. When I am running
"pvbatch --use-offscreen-rendering script_file.py", I get the following
error:
------------------------------------------------------------------------------------------------------------------------
[fe02s01:15756] *** Process received signal ***
[fe02s01:15756] Signal: Segmentation fault (11)

Segmentation fault (core dumped)

What is going wrong? Is there any problem with the installation of my
Paraview with OSMesa support? This pvbatch works fine without
--use-offscreen-rendering option when I "ssh" with the "-X" option.

Thank you,
Pradeep
