As this bug-report is mainly for documenting the problem: Another way to fix the problem is to backport gnupg2 and libgpg-error from unstable.
As far as I can tell this works without problems (conflicts). This fixes decryption issues (commit 798daaa1ddf73f64cf840fbdc1f4c5b9c4b4ec13) and other problems with OpenPGP cards too. Don't forget to do a gpg2 --card-edit fetch and gpg2 --card-status for updating key-infos. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
