I am using the 2.0 preview, although i am in the process of compiling the svn
head code.

Yes the problem is due to when the BeginUpdate and the EndUpdate is called.
Changing the example to what is below causes the error to occur.
MS .NET works in this case.

using System;
using System.Windows.Forms;

public class test
        static void Main ()
                Form f = new Form ();

                ListView lv = new ListView ();
                for (int i = 0; i < 20; i++)
                        lv.Items.Add ("Item " + i);
                lv.EnsureVisible (16);

                lv.Parent = f;
                f.Load += delegate { lv.EnsureVisible (16); };

                Application.Run (f);
