#16 pdf_open_PDF_page gives Entry 4 is outside range the range

[Anonymous]

I try to use an existing PDF SpecificationTemplate.pdf as PDF form.

Here is the code:
{pdf_inc.i "THIS-PROCEDURE"}
RUN pdf_new ("Spdf","tmp/extract.pdf").
RUN pdf_new_page("Spdf").
RUN pdf_open_PDF("Spdf","dump/SpecificationTemplate.pdf","Inv").
RUN pdf_close("Spdf").

This gives the following error: Entry 4 is outside range of list /Fontname/BAAAAA+Tahoma. (560)

I use PDFInclude 3.3.3. I have attached the PDF file.

How can this problem be solved?
