+Summary: TreeView: NRE in TreeView.EndEdit
+
+After editing a treeview label/text EndEdit causes a NRE (see NRE below).
+
+If you select an other node during edit, edit doesn't get canceled instead
+the new node gets selected and the "edit node" is still in edit mode (wow,
+what a sentence :-)
+
+Btw, TreeNode.EnsureVisible() doesn't work either.
+
+Attached is a test case that works fine on windows.
+
+Unhandled Exception: System.NullReferenceException: Object reference not
+set to an instance of an object
