Description of problem:
I can't launch "File" (a.k.a. Nautilus) on a "Gnome+Wayland" session. The terminal returns the following output:

"""
(nautilus:3220): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed

(nautilus:3220): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed
Failed to register: È stato raggiunto il timeout

"""

"È stato raggiunto il timeout" may be translated as "timeout reached".
