Saver progress bar is not displayed with png in Gimp git 3.1.5

Arch Linux
Gimp git 3.1.5
I copied saver.py in ~/.config/GIMP/3.1/plug-ins/saver
It doesn't work

What does "it doesn't work" mean? What happens? Does it print any error messages? Is ~/.config/GIMP/3.1/plug-ins/saver/saver.py executable? I use saver a lot myself, and it's working fine for me under the current GIMP from git master.

Gimp commit ff4250df
saver.py is executable, of course
Last observation result:

• Example with png files: file -> saver . It seems apparently saver doesn't work after .png files luminosity changing because no progressed bar is displayed in Gimp. But after that, i see luminosity change has been saved ( in Gimp or Digikam). So, issue comes from progress bar not displayed in Gimp.
• Saver works normally with jpg and xcf, progress bar is displayed
• I did not tested with other file formats.
