Good point! That was indeed the problem: The PDF was not allowed to be modified. I fixed the write-permission issue by copying the content via the `qpdf` command line program:

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.
