Gtk.NodeView(NodeStore) constructor does not work (but NodeStore property does)

[dafrito]

Steps to Reproduce

Follow the steps in https://www.mono-project.com/docs/gui/gtksharp/widgets/nodeview-tutorial/

Short version:

1. Create and show a Gtk2 Window that has within it a NodeView.
2. When creating the NodeView, assign the Store in the constructor or by setting the NodeStore property.

using System;
using Gtk;

namespace NodeViewTutorial {

[Gtk.TreeNode (ListOnly=true)]
class MyTreeNode : Gtk.TreeNode {
    string song_title;

    public MyTreeNode (string artist, string song_title)
    {
            Artist = artist;
            this.song_title = song_title;
    }

    [Gtk.TreeNodeValue (Column=0)]
    public string Artist;

    [Gtk.TreeNodeValue (Column=1)]
    public string SongTitle {get { return song_title; } }
}

public class NodeViewExample : Gtk.Window {
    public NodeViewExample () : base ("NodeView")
    {
        SetSizeRequest (200,150);

        // Create our TreeView and add it as our child widget
        Gtk.NodeView view = new Gtk.NodeView (Store());
        Add (view);

        // Create a column with title Artist and bind its renderer to model column 0
        view.AppendColumn ("Artist", new Gtk.CellRendererText (), "text", 0);

        // Create a column with title 'Song Title' and bind its renderer to model column 1
        view.AppendColumn ("Song Title", new Gtk.CellRendererText (), "text", 1);
        view.ShowAll ();
    }

    protected override bool OnDeleteEvent (Gdk.Event ev)
    {
        Gtk.Application.Quit ();
        return true;
    }

	Gtk.NodeStore store = null;
	private Gtk.NodeStore Store() {
        if (store == null) {
            store = new Gtk.NodeStore (typeof (MyTreeNode));
            store.AddNode (new MyTreeNode ("The Beatles", "Yesterday"));
            store.AddNode (new MyTreeNode ("Peter Gabriel", "In Your Eyes"));
            store.AddNode (new MyTreeNode ("Rush", "Fly By Night"));
        }
        return store;
    }

	public static void Main ()
	{
			Gtk.Application.Init ();
			NodeViewExample win = new NodeViewExample ();
			win.Show ();
			Gtk.Application.Run ();
	}
}
}

Current Behavior

If the constructor is used to set the NodeStore, no values appear.

If the NodeStore property is used to set the NodeStore, the values appear as in the demo.

Expected Behavior

The constructor should behave the same as the NodeStore property.

I get this error on xubuntu 18.04...
gtk-sharp2: Installed: 2.12.45-0xamarin14+ubuntu1804b1
Mono JIT compiler version 5.18.1.3
Just to spell out the workaround...

            _nodeView = new NodeView();
            _nodeView.NodeStore = nodeStore;

NB: I am also experiencing issue #267 "NodeView.NodeStore setter not changing underlying field"
