Comment # 24 on bug 1226112 from Wolfgang Rosenauer

Sorry, I don't know. There are quite a few people with different setups that
enforcing xdg-desktop-portal is broken for them.

I have NO experience about xdg-desktop-portal! Maybe something is broken in the
XDG support on openSUSE or just in the users' setup. I have no idea. The only
option for me right now was to not use it anymore until someone can tell that
it works correctly.

The same change will follow for Firefox.

Afterwards I will see if I can create a patch for Firefox so that it only
enforces xdg-desktop-portal for KDE/Plasma but this is not guaranteed.
