Comment # 8 on bug 1215641 from Maurizio Galli

I have prepared a patched package [0] for Xfce with the drop-in file however it
does not seem to work.

[0]https://build.opensuse.org/package/show/home:mauriziogalli:branches:X11:xfce/xfce4-session

flatpak applications still get errors such as `Args: No such interface
“org.freedesktop.portal.FileChooser”`
