Package: python-gnupg Version: 0.4.3-1 GnuPG can live happily with fingerprint collisions, but python-gnupg cannot. Here a user of Gajim had a problem because of the check: https://paste.debian.net/1050481/
Upstream has already fixed this in master. IMHO it's worth to put the commit as a patch in the Debian package: https://bitbucket.org/vinay.sajip/python-gnupg/commits/9cb2a856677237b528ead6fff68de7d488dbfeec
