Aspose.PDF - AddStamp error "Unable to read beyond the end of the stream."

I am trying to stamp a PDF document and receiving the error. Other PDFs work fine.

Code sample:
saveFileName = Path.Combine(filePath, fileName);

            document = new Aspose.Pdf.Document(saveFileName);

            textStamp = new TextStamp(stamp);
            textStamp.XIndent = xPos;
            textStamp.YIndent = yPos;
            textStamp.TextState.Font = FontRepository.FindFont(fontName);
            textStamp.TextState.FontSize = fontSize;

            foreach (Page docPage in document.Pages)
            {
                docPage.AddStamp(textStamp);
            }

            //Save with stamp
            document.Save(saveFileName);
            document.Dispose();

Error message: Unable to read beyond the end of the stream.
