No thumbnails in nautilus

[sebB]

Hello,

Using gnome-light 3.30 and nautilus don't display thumb from image files or pdf.

Il I open an image with gimp, the thumbnail is create.

I have a lot of files in .cache/thumbnails/fail/gnome-thumbnail-factory

According to https://bugs.gentoo.org/653786 , I need bubblewrap and gdk-pixbuf. Bof are installed on my system.

Do I need some extra package?

I'm on stable system with gnome-light 3.30 unmasked

Thanks
