Bug#836170: evince: annoying Gtk-WARNING messages

[Vincent Lefevre]

Package: evince
Version: 3.20.1-1
Severity: normal

When I run evince from a terminal, I get the following annoying
Gtk-WARNING messages:

(evince:25632): Gtk-WARNING **: Failed to get the GNOME session proxy: The name org.gnome.SessionManager is not owned

(evince:25632): Gtk-WARNING **: Failed to get the Xfce session proxy: The name org.xfce.SessionManager is not owned

(evince:25632): Gtk-WARNING **: Failed to get an inhibit portal proxy: The name org.freedesktop.portal.Desktop is not owned

For the first two, this is completely stupid: I use neither GNOME,
nor Xfce! I don't know about the third one (I just use fvwm as my
window manager).
