This question already has an answer here:

When trying to open nautilus (from the Launcher or from the Dash pressing on Files), it does not open, and the desktop aren't responding.

The output of nautilus -q (without sudo):

(nautilus:12039): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed
(nautilus:12039): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed
Could not register the application: Timeout was reached
(nautilus:12039): Gtk-CRITICAL **: gtk_icon_theme_get_for_screen: assertion 'GDK_IS_SCREEN (screen)' failed
(nautilus:12039): GLib-GObject-WARNING **: invalid (NULL) pointer instance
(nautilus:12039): GLib-GObject-CRITICAL **: g_signal_connect_object: assertion 'G_TYPE_CHECK_INSTANCE (instance)' failed

If i use gksu nautilus it opens but with an error:

(nautilus:18320): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed

Currently fixing this issue by restart my PC or by restart nautilus:

sudo killall nautilus && (nautilus &)

But is just a temporary fix.

    Why do you use sudo for Nautilus? – David Foerster Nov 1 '16 at 9:27
  • You right. i changed it – Benny Nov 1 '16 at 9:30
  • Since you removed sudo from your post now, do you get the same results with nautilus -q (without sudo)? (Contact me in chat if you think this is going to lead to extended discussion unsuitable for the comment section.) – David Foerster Nov 1 '16 at 9:34

    If you always used sudo, that would explain the problem of its not launching. Please edit your question and clarify whether this only happens when using sudo. Also explain how you try to open nautilus and when you are doing it. Is it after rebooting or after waking up from suspend? – terdon Nov 1 '16 at 9:51
  • i am not using sudo to open nautilus. i am not suspend my PC, after rebooting nautilus always working properly, it happens once or several times a day. – Benny Nov 3 '16 at 9:36
