        Hi,
I just noticed I see this when running GNOME under Xorg and when
opening new composer window (Ctrl+N). It doesn't do that when running
GNOME under Wayland, neither when running for example MATE, which also
uses X11.

The backtrace of the warning is below and it shows it is in glib's
GDBus code. What or why I do not know, neither consequences of it; I do
not know glib code.
        Bye,
        Milan
