Ok, attaching the patch.  These are the steps I followed to test it:

 0. Apply the patch.

 1. Add ``python-gpg`` at the end of ``gnu/packages/gnupg.scm`` (sorry
    for my poor Scheme habilities).

 2. Run ``guix environment --ad-hoc -l gnu/packages/gnupg.scm python
    assword coreutils``.

 3. Import ``gpg`` in Python and check ``gpg.version.versionstr``, dump
    ``assword`` program to verify that it uses the same build of
    ``python-gnupg``.

 4. Run ``assword`` and check that everything works.

Probably many steps can be done better/more easily, but my knowledge is
very limited.  Links for improving that are welcome.`;)`

Thanks and cheers,
