The log-file you sent me contains the following line:

Thu Mar 24 11:05:53 2011  [DEBUG] file already pdf, simply copying it
(cp /var/spool/cups-pdf/SPOOL/cups2pdf-12256 /home/jpht/tmp/PDF/Bugs_in_package_cups-pdf_--_Debian_Bug_report_logs.pdf)

This option to directly copy PDF instead of reprocessing it was
suggested to me some time back and I decided not to implement it since
it would disable all options set in cups-pdf.conf on the respective
files. This is exactly what happens to you here: the PDF is just passed
through instead of getting re-worked with all your desired options by
CUPS-PDF.

So, speaking for upstream: no fix needed.
My advise to the distribution: remove this additional patch on CUPS-PDF
since it breaks basic functionality.
