[IronPython] Ironpython 2 Alpha 4

[David.Lawler at franke.com]

The following ugly hack works fine with IronPython 1.1 and with 2.0 alpha 
3 but raises an exception on line 28 with IronPython 2.0 alpha 4.
To run this you need a copy of the ICSharpCode.TextEditor.dll from 
SharpDevelop (http://www.icsharpcode.net/OpenSource/SD).
Is this a bug or a new 'feature'?  Is there a work-around?  Thanks.   DJL
