--- Comment #2 from Jan Kundrát <j...@kde.org> ---
I'm having lots of fun so far.
I did some debugging and it seems to me that my gpg-agent started deadlocking:

...so I noticed that I can update dev-libs/npth from 1.2 to 1.3, but the test
was still failing (after making sure that I kill all GnuPG Leftovers in between
attempts). I noticed that it doesn't appear to deadlock, though, so I increased
the timeout for gpg-agent to do its job form 10s to 20s, went back to npth 1.2,
and boom, it started working. However, it takes aaaaaaages (12s for that tets
on my system).
If the gpg-agent remains running in between attempts, the subsequent runs
succeed much faster.
Working hypothesis: maybe gpg-agent now needs some extra time for its
first-time init?
