Font parsing exception

[DanRoche]

I'm using Freespire.Office and get a font parsing exception error on the SaveToFile line, but only if I'm also using the code below to check if there are images. If I comment that block out, or close the document and reopen it after the for loop, I don't get the error.

doc.LoadFromFile(FileWithPath);
foreach (PdfPageBase p in doc.Pages)
{
Image[] images = p.ExtractImages();
if (images != null && images.Length > 0)
HasPicture = true;
}

doc.SaveToFile(DOCX, Spire.Pdf.FileFormat.DOCX);

Inner Exception 1:
ArgumentNullException: Buffer cannot be null.

I have it working, but it means I have to close it and re-open it to save it as another format.
