Public bug reported:
I have a script that changes my wallpaper on a regular basis. It sets
the wallpaper using gsettings. Like this:
file=/home/lincoln/Pictures/wallpaper/10-2.jpg
gsettings set org.gnome.desktop.background picture-uri file://$file
gsettings set org.gnome.desktop.screensaver picture-uri file://$file
Every time this happens, I get an error in my system log.

Nov 23 08:50:23 imrlincoln gnome-shell[2678]: Object Meta.Background
(0x55ad39916a20), has been already deallocated - impossible to access to it.
This might be caused by the fact that the object has been destroyed from C code
using something such as destroy(), dispose(), or remove() vfuncs

This does not seem to cause any actual issues, but since this happens
every 5 minutes, it does cause my system log to get large.
I tried to track down the actual code mentioned in the error, but it
doesn't seem to exist anywhere on the filesystem.
