We are using the pdfexporter and implementing the following code

PdfExporter exporter = new PdfExporter();
pdfExporter.Export(diagram, fileName); 

to export PDF's.  When we call this code to export a diagram containing a ShapeNode using a Shape drawn by code written by us, we get an exception from within the Mindfusion code base.
The Shape code we use is:

Shape shape = new Shape(
		   new ElementTemplate[]
		   { new LineTemplate(50, 0, 100, 30),
			  new LineTemplate(100, 30, 100, 70),
			  new LineTemplate(100, 70, 50, 100),
			  new LineTemplate(50, 100, 0, 70),
			  new LineTemplate(0, 70, 0, 30),
			  new LineTemplate(0, 30, 50, 0)
		   },
		   new ElementTemplate[]
		   {
		   },
		null, System.Drawing.Drawing2D.FillMode.Winding, "Gateway");
		ShapeNode node = diagram.Factory.CreateShapeNode(xPos, yPos, 75, 15, shape);
		  node.Brush = new MindFusion.Drawing.SolidBrush(nodeColor);
		node.Font = new System.Drawing.Font("Verdana", 2.4F, GraphicsUnit.World);
		node.CustomDraw = CustomDraw.Additional;
		node.Pen.Brush = new MindFusion.Drawing.SolidBrush(Color.Black);
		node.Pen.Width = 0;
		node.ShadowColor = Color.Black;
		node.ShadowOffsetX = .8f;
		node.ShadowOffsetY = .8f; 

The exception is occurring with us using AcrobatReader Version 8, and either PdfExport.dll versions 5.0.3.20105 or version 5.0.2.29231.

Is there a workaround to avoid getting this error during a pdf export? Or are we doing something wrong in the drawing of the Shape? Your assistance is greatly appreciated.
