Chart data extraction throws exception

Hi,

I am getting exception in few cases when trying to read chart workbook and related properties. Need access to workbook to read and modify data effectively.
Method Chart.ChartData.ChartDataWorkbook.GetCell(1,1,1) is working but GetRange, GetCellCollection etc fails.

Code:

   using (var p = new Presentation("/app/ppt/Testppt.pptx"))
    {	
    	foreach (var sld in p.Slides.ToList())
    	{                    
    		var chs = sld.Shapes.OfType<Chart>().ToList();
    		chs.ForEach(ch =>
    			{
    				try
    				{
    					ch.ChartData.GetRange();
    				}
    				catch(Exception ex)
    				{
    					;
    				}                               
    			});
    	}
     }

exception:
Chart data doesn’t have workbook reference.
