Comment # 1 on bug 1224070 from Gerardo Gomez Rodriguez

Hi Martin,
This looks to be fixed already, as seen here:
https://build.opensuse.org/package/rdiff/devel:microos/plasma-branding-MicroOS?linkrev=base&rev=18.
Basically 2 new servicemenus were created: extract and compress to mimic the
normal integration (only RPM or only Flatpak installations).

If this is not working for you out-of-the-box, it could be because your user
was created BEFORE this change was introduced, therefore the user did not
inherit the /etc/skel from the commit. If you want to have the integration
working you could:

1. Make sure you have plasma-branding-MicroOS package (I did not have it,
because I probably removed it by accident).
2. cp -r /etc/skel/.local/share/kio/ ~/.local/share/
