Code:
qpdf --empty --pages <original.pdf> -- writable.pdf
Then I copied writable.pdf into the calibre database.

This is certainly not perfect, because I loose possible metadata from the original PDF, but at least I can export the PDF with the metadata from calibre.
Good to hear that you found a workaround.
