I'm a big noob in Gtk#, but i'll try to help.

Are you sure the error is there? I say it becouse your code example works in 
my workstation. See the next code:

using System;
using Gtk;

namespace deleteme
{
	public class EmptyWindow : Gtk.Window
	{
		public EmptyWindow() : base(WindowType.Toplevel) {
			Button b = new Button("Do something");
			b.Clicked += HandleBClicked;
			
			Button b2 = new Button("Do other thing");
			b2.Clicked += HandleB2Clicked;
			
			HButtonBox box = new HButtonBox();
			box.PackStart(b, false, false, 0);
			box.PackStart(b2, false, false, 0);
			this.Add(box);
			this.Title = "Lame example";
			this.ShowAll();
		}

		void HandleBClicked (object sender, EventArgs e) {
			MessageDialog md = new MessageDialog(this, DialogFlags.Modal, 
MessageType.Error, ButtonsType.Close, "Some error");
			md.Response += delegate(object o, ResponseArgs args) {
				if (args.ResponseId == ResponseType.Close)
					Console.WriteLine("Response: Closed");
				else
					Console.WriteLine("Other response happened.");
			};
			md.Run();
			md.Destroy();
		}
		
		void HandleB2Clicked (object sender, EventArgs e) {
			MessageDialog md = new MessageDialog(this, DialogFlags.Modal, 
MessageType.Error, ButtonsType.Close, "some error");
        
			md.Run ();
			// <-- here, I would like to stop and wait for dialog to be closed 
			md.Destroy();
		}

	}
}

There you have the example I was writing to ilustrate the technique and your 
code example. Both works for me. In fact they are actually pretty much the 
same, but using a delegate to receive the response event and destroying the 
dialog just after run().

Maybe you are hitting some bug?
