GNOME Bugzilla – Bug 636548
Wallpapers / backgrounds disappear or are removed/deleted from backgrounds.xml

This is something I've been seeing for years. There seems to be some kind of weird logic going on where gnome-appearance-properties silently purges any wallpapers I added to it. I often add wallpapers by drag and drop, sometimes with the Add button. I couldn't figure out why they usually disappear after a while, leaving only the "active" (currently used) wallpaper + the system-wide-installed wallpapers ; even if my actual wallpaper files in Images/wallpapers haven't changed at all!
I just tested this again with 2.32 to make sure: added a bunch of wallpapers to gnome-appearance-properties on december 5th. They were still there yesterday and the days before, but now (december 9th), they have disappeared; all the wallpapers except - the currently used one - the ones that are installed systemwide (ubuntu's wallpapers) So, every 3-4 days, wallpapers get purged.
Did you by any chance open the appearance panel, and not go to the backgrounds page? (bug 634156)
Indeed. *** This bug has been marked as a duplicate of bug 634156 ***
