+Summary: ColumnHeader.Text should work after the ListView is disposed
+
+Description of Problem:
+Setting Text on a ColumnHeader that was added to a ListView which was 
+later disposed throws an exception.
+
+Steps to reproduce the problem:
+Compile and run the following program:
+using System;
+using System.Windows.Forms;
+class Test {
+    static void Main() {
+        ListView l = new ListView();
+        l.View = View.Details;
+        ColumnHeader c = new ColumnHeader();
+        l.Columns.Add(c);
+        l.Dispose();
+        c.Text = "";
+    }
+}
+Actual Results:
+An exception.
+
+Expected Results:
+No exception.
+
+How often does this happen? 
+Always (on the SVN version).
+
+Additional Information:
+The exception is thrown because setting the text tries to update the 
+ListView. I suggest adding a check in ColumnHeader.Text:
+if (owner != null && !owner.IsDisposed). This applies to many other 
+properties.
