Wayland use under Gnome 3.26 or above leads to crash on Navbar click

[refdoc]

This is now a clarified version of #844

Gnome 3.26, 3.28 both use - at least on Debian - Wayland as the standard compositor. It is this combination which leads to the crash described in #844 Switching to X makes the programme behave normal.

On Gnome 3.28 the terminal output reads as follows:

(xiphos:28995): Gdk-CRITICAL **: 10:25:50.570: gdk_window_get_window_type: assertion 'GDK_IS_WINDOW (window)' failed
**

widget_anchor and menu_anchor for gtk_menu_popup_at_widget should not be 0, now it works on wayland.
