Commented Unassigned: Excel crashes after Open and save as [15566]

after this simple piece of code the excel to load this file.

```
[TestClass]
public class UnitTest1
{

private string TemplateFileName = @".\templates\TestWithPivotTablePointingToExcelTableForData.xlsx";
private string ExportFileName = @".\templates\TestWithPivotTablePointingToExcelTableForData_Export.xlsx";

[TestMethod]
public void TestWithPivotTablePointingToExcelTableForData()
{
using (ExcelPackage excelpackage = new ExcelPackage(new FileInfo(TemplateFileName), true))
{
excelpackage.SaveAs(new FileInfo(ExportFileName));
}

}
}
```

as far as i can tell it occures when there is a pivottable in the sheet which points to an exceltable as datasource.

In the attachments i've added an example file.
