The org.gnome.Mutter name is not on the system bus, since it's your
compositor's instance and it's running in your session.

The default for `dbus-send` is to use the session bus. The equivalent for
`gdbus` is to use the `--session` argument; you're using `--system`, which
is meant for the system bus.

For instance, this:

```
$ gdbus call --session \
> --dest org.gnome.Mutter.IdleMonitor \
> --object-path /org/gnome/Mutter/IdleMonitor/Core \
> --method org.gnome.Mutter.IdleMonitor.GetIdletime
(uint64 29,)
```

will return the appropriate result with no warnings.

Ciao,
 Emmanuele.
