All icons disappear, and the desktop doesn't react to mouse input. nautilus throws the following error: (nautilus:3723): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed (nautilus:3723): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed This is relevant since e.g. the Dropbox indicator calls nautilus this way, resulting in the desktop crashing.
