Comment 2 for bug 1896138

as an update, this is still broken on 20.10. as well, I've noticed an interesting detail, which is that thumbnailing *is* working on my connected Google Drive. so it really does just seem to be samba shares.

As well, I've discovered that if I remove the `/home/tessa/.cache/thumbnails/fail/gnome-thumbnail-factory` directory, then when I reload a samba dir with images in it in nautilus, and creates a bunch of PNGs in it for the number of thumbnails it's failed to generate from the network share, and all id by file as "PNG image data, 1 x 1, 8-bit/color RGBA, non-interlaced". So it's definitely trying to create the thumbnails, and then failing in some way.

is there any feedback on how to debug this further and find out why it's failing? is there a way to get nautilus to log what it's doing here for further inspection?
