Ubuntu 18.04 - Object Meta.Background (0x558f160bd6e0), has been already deallocated - impossible to access to it

This is on Ubuntu 18.04.1LTS with Gnome-Shell: gnome-shell: Installed: 3.28.2-0ubuntu0.18.04.1 Candidate: 3.28.2-0ubuntu0.18.04.1

Wallpaperdownloader wallpaperdownloader 3.1

I have it set to change wallpapers every 10 minutes. Every 10 minutes when the wallpaper is changed this is written to syslog:

Aug 21 07:18:17 localhost gnome-shell[2443]: Object Meta.Background (0x558f160bd6e0), 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 Aug 21 07:18:19 localhost org.gnome.Shell.desktop[2443]: == Stack trace for context 0x558f13f1a320 == Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #0 0x558f143bd618 i resource:///org/gnome/shell/ui/background.js:718 (0x7fe39430f450 @ 22) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #1 0x558f143bd590 i resource:///org/gnome/shell/ui/tweener.js:113 (0x7fe3946c7e68 @ 37) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #2 0x7ffd823b7800 b resource:///org/gnome/gjs/modules/tweener/tweener.js:208 (0x7fe3946d3b38 @ 54) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #3 0x7ffd823b7950 b resource:///org/gnome/gjs/modules/tweener/tweener.js:337 (0x7fe3946d3bc0 @ 1626) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #4 0x7ffd823b7a00 b resource:///org/gnome/gjs/modules/tweener/tweener.js:350 (0x7fe3946d3c48 @ 100) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #5 0x7ffd823b7a90 b resource:///org/gnome/gjs/modules/tweener/tweener.js:365 (0x7fe3946d3cd0 @ 10) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #6 0x7ffd823b7b80 b resource:///org/gnome/gjs/modules/signals.js:128 (0x7fe3946d3230 @ 386) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #7 0x7ffd823b7c30 b resource:///org/gnome/shell/ui/tweener.js:245 (0x7fe3946cf808 @ 159) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #8 0x7ffd823b7d00 b resource:///org/gnome/gjs/modules/_legacy.js:82 (0x7fe3946b5de0 @ 71) Aug 21 07:18:20 localhost org.gnome.Shell.desktop[2443]: #9 0x7ffd823b7da0 b resource:///org/gnome/shell/ui/tweener.js:220 (0x7fe3946cf780 @ 15)

This is easily reproducible by starting wallpaperdownloader and monitoring the syslog output. I believe this is more of a minor issue than a major one as the app works as it's supposed to.
