[Paraview] pv_web_visualizer.py segmentation fault when loading a pvsm file

[Sebastien Jourdain]

Hi Pepe,

I am not aware of the issue do you mind sharing your state file with me so
I can see what you were doing in your state file?

Did you generate your state file from the Visualizer or ParaView?

Thanks,

Seb
