[Paraview] PV 3.12.0 unable to save screenshot as a PNG file

[Richard GRENON]

Hello, all.

I have downloaded the final Paraview 3.12.0 Linux x86 64 bits binaries. 
I have tested several screenshots with different image formats.
I can save screenshots as jpg, bmp or tif files, but I cannot save 
screenshots as PNG files. Following is the error message for PNG format:
>
> ERROR: In 
> /home/kitware/Dashboards/MyTests/ParaView-master/VTK/IO/vtkPNGWriter.cxx, 
> line 199
>
> vtkPNGWriter (0x14371f10): Unable to write PNG file!
>
This seems to be the same problem that Gena Bug reported for PV 3.12.0 RC3

Not yet tested the Windows version.

Best regards.
