Corrupted version of plasma-org.kde.plasma-desktop-appletsrc
from time to time I see an issue where settings in ~/.config/plasma-org.kde.plasma-desktop-appletsrc seem to get silently removed somehow without doing any configuration change related to them.
This has visibly affected pinned launchers in my panel (icon-only-task-manager) and my desktop wallpaper.
It happens the following way: Suddenly when I have logged in after boot I find the wallpaper being reseted to a default one and some of my pinned launcher icons in the panel are suddenly missing - while everything was ok when I last logged out.
This has happened the same or a very similar way for 3-4 times, with roughly 1-3 months between the incidents. Unfortunately I haven't found a way to reproduce this since from my point of view this happens "out of nowhere".
I found out that deletions in plasma-org.kde.plasma-desktop-appletsrc are responsible for the missing launchers/changed wallpaper, so I'm attaching:
- the "corrupted" version of the respective file
- the version restored from a three-day-old backup
- the diff between the two versions
While I'm reporting this bug from Kubuntu 20.04 (without backport PPA), I have also seen this on Kubuntu 19.10 with backport PPA (and maybe even 19.04).
Is there anything I can do to help debugging this issue?

This is how it should be.
