can't set picture as desktop wallpaper in nautilus

[Erald Bardhi]

When right-clicking a picture in nautilus, and then clicking on the 'Set as Background...' option from the menu, it doesn't do anything. The wallpaper can be changed from the image viewer though.

Thank you for your bug report. Do you get any error printed if you start nautilus from a commandline ? It's supposed to the use desktop portal for setting the wallpaper so maybe that's not working as expected from some reason...

I submitted another bug about nautilus, that also affects other system apps like the snap store, settings and text editor, about the apps not adhering to the dark theme when opened. I've noticed this only happens when I open those apps almost straight away after I've booted into the desktop, when I wait a couple of minutes after boot before opening the apps, they are displayed in dark mode as expected. The 'Set as Wallpaper...' bug only occurs when I open nautilus after boot and it's displayed in light mode. My system theme is 'Dark Style'.
There's no errors when I open nautilus from the terminal. Here's the output:

** Message: 12:01:54.577: Connecting to org.freedesktop.Tracker3.Miner.Files

I'm using the nvidia driver 535.171.04 and X11.
