Null reference exception when saving certain XLS files

Using Aspose.Cells 8.0.1, attempting to save the attached xls file to PDF will cause a CellsException to be raised with a null reference exception message.


[Fact]
public void Aspose_Cells_SaveToPdf_NRE()
{
var tempFile = Path.GetTempFileName();

try
{
var workbook = new Aspose.Cells.Workbook(@".\AsposeTests\TestData\8DB5CEB635567E42D0F1232397B568983E904BA1.xls");
workbook.Save(tempFile, Aspose.Cells.SaveFormat.Pdf);
}
finally
{
File.Delete(tempFile);
}
}
