Comment 9 for bug 344228

In my opinion, this is not a real bug.

If you delete an image, it can no longer be opened. That's true for every file.

As the original poster stated, his wallpaper changed immediately. So he can restore the file from trash and learned his lesson, no harm done.

But on the other hand I can kind of understand the usability implications of this.

If this is supposed to get solved, then I suggest the following solution:

The thumbnail viewer when changing the background will show the files in /usr/share/backgrounds and ~/.local/share/backgrounds

If a new wallpaper gets chosen it is copied to the user folder, the button "Remove" in the wallpaper dialog gets replace with a "Delete" button

This is pretty much the same behaviour as the theme chooser btw.

The implementation however doesn't seem trivial to implement, so I am not sure if this is really a papercut
