+Make it possible to run firefox with KDE filedialogs.
+
+The call for parse_app_info_from_flatpak_info uses the /proc/$PID/root
+file to access the flatpak information file.
+
+We neither have support for /proc/$PID/root nor flatpaks or snaps.
+
+With this fix and deskutils/plasma5-xdg-desktop-portal-kde it is now possible
+to run firefox using the KDE file dialogs.
+
+> GTK_USE_PORTAL=1 firefox
