[Mono-list] GTK# problem

[chris at jib.co.za]

Hi all,

I have a problem with an gtk# app. As soon as I define a signal, at this
stage it  is <signal name="delete_event" handler="on_mainGUI_delete_event"
last_modification_time="Sat, 23 Sep 2006 14:53:03 GMT"/>, in the glade.xml
file, the following Exception is raised:

Object reference not set to an instance of an object.

ConnectFunc()
Autoconnect()
Autoconnect()
.ctor()
Main()

My code looks like this:
---
using Gtk;
using Glade;
using System;

namespace Sharp
{
	/// <summary>
	/// Description of MainWindow.
	/// </summary>
	public class MainWindow
	{
		public MainWindow()
		{
			Glade.XML gxml = new Glade.XML(null, "Sharp.glade.xml", "mainGUI", null);
			gxml.Autoconnect(this);
		}

		[STAThread]
		public static void Main(string[] arg)
		{
			Application.Init();
			new MainWindow();
			Application.Run();
		}

		void on_mainGUI_delete_event(object o, DeleteEventArgs args)
		{
			Application.Quit();
			args.RetVal = true;
		}
	}
}
---

All ideas appreciated.
Chris
