Plugging the GtkSocket icon can fail, in which case NaTrayManager emits tray-icon-removed but the icon has never emitted plug-added, thus the ShellTrayIcon has not been created. This results in various criticals and exceptions in the tray-icon-removed handler. https://bugzilla.gnome.org/show_bug.cgi?id=633028
