Is it problem in PyPdf?
The pdf document is created by AutoCAD. The not worked pdf file example: http://narod.ru/disk/25146194000/1.pdf.html

it is probably a problem with pypdf. It seems that the developer of pypdf is not actively maintaining this library so if anyone could hack on pypdf and fix such issues, this would be a great help.
