 Marking as blocker, we can't very well release with this, it would be
 embarassing.

 Confirmed;  I also get this error with current CVS;  It did not appear
 with two weeks ago before I went to Guadec in Ireland.

+Ok, i have a simpler test case:
+The StringReader part is *not* triggering the bug, but reading from a
+file is.
+
+using System;
+using System.Xml;
+using System.IO;
+
+class T {
+
+	public static void FromStringReader ()
+	{
+		StringReader s = new StringReader (
+			@"<?xml version='1.0'?>
+			<a>
+			<b />
+			</a>");
+		
+		XmlTextReader r = new XmlTextReader (s);  
+		while (r.Read ());
+	}
+	
+	public static void FromFile ()
+	{
+		XmlTextReader r = new XmlTextReader ("file.xml");  
+		while (r.Read ());
+	}
+	
+	public static void Main ()
+	{
+		Console.WriteLine ("Both tests should give no warnings");
+		Console.WriteLine ("Beginning tests that reads from file");
+		for (int i = 0; i < 50; i++) {
+			FromFile ();
+		}
+		Console.WriteLine ("Beginning tests that reads from StringReader");
+		for (int i = 0; i < 50; i++) {
+			FromStringReader ();
+		}
+		Console.WriteLine ("Done");
+	}
+}
