+Summary: Problems with GDIPlus
+
+Description of Problem:
+I've been trying to use Dundas Chart for .NET (www.dundas.com) with Mono 
+but I experienced some problems. I already installed the mono-drawing, 
+gdiplus, etc package but when I run with 'mono Dundas.exe'
+
+Unhandled Exception: System.NullReferenceException: Object reference not 
+set to an instance of an object
