Hi!

We need the PDF file to investigate the issue.

Hi!

The file is not corrupted, but contains an unusual name/value pair.

Here's a fix for that: in PdfRectangle.cs (2 new lines):
Code:
internal PdfRectangle(PdfItem item)
{
  if (item == null)
    return;

  // 2 new lines below:
  if (item is PdfNull)
    return;
  // 2 new lines above

  if (item is PdfReference)
    item = ((PdfReference)item).Value;

  PdfArray array = item as PdfArray;
  if (array == null)
    throw new InvalidOperationException(PSSR.UnexpectedTokenInPdfFile);

  this.x1 = array.Elements.GetReal(0);
  this.y1 = array.Elements.GetReal(1);
  this.x2 = array.Elements.GetReal(2);
  this.y2 = array.Elements.GetReal(3);
}


This is not the solution for all "unexpected token" errors, but at least for one.
