[pkg-gnupg-maint] Bug#854616: scdaemon cannot access yubikey using ccid driver without pcscd

Package: scdaemon
Version: 2.1.18-3
Severity: grave
In Bug#854005, I have described a distinct issue I have experience
with my Yubikey since the upgrade of the GnuPG suite from 2.1.17 to
2.1.18, and in the case of pcscd, from 1.8.19-1 to 1.8.20-1.
I am not sure what exactly is going on here. What I know is that I was
able to configure my Yubikey to work in Jessie with GnuPG using a
procedure I have documented here:
https://anarc.at/blog/2015-12-14-yubikey-howto/
After installing a new workstation with Debian stretch, things were
still working until the 2.1.18 release.
The symptom is this:
[996]anarcat at curie:~$ LANG=C gpg --card-status
gpg: selecting openpgp failed: No such device
gpg: OpenPGP card not available: No such device
At first, adding "disable-ccid" to scdaemon.conf fixes the issue. But
after a while, the behavior returns.
I have noticed that pcscd is gone when that happens. After advice
received in 854005, I have tried to uninstall pcscd to try and let
scdaemon handle the device. This also fails. Here's a trace of me
purging pcscd, restarting gpg-agent and trying to connect to the card.

Those were enabled with:
printf 'debug-all\nlog-file /run/user/%d/scdaemon.log\n' "$(id -u)" >> ~/.gnupg/scdaemon.conf
If I reinstall pcscd and disable-ccid in scdaemon.conf, things work
again, for a while, until pcscd crashes again.

I haven't figured out what happens when pcscd crashes - i couldn't
find anything in the syslog or anywhere.
I get this error from scdaemon:
fév 06 19:45:29 curie gpg-agent[1643]: scdaemon[1645] pcsc_establish_context failed: no service (0x8010001d)
... which is the same error as when pcscd is uninstalled - ie. it's
not running.
the reason why reinstalling pcscd fixes the issue for me is probably
that it resets the systemd configuration for the daemon and
reinstalling restarts it properly.
now it is running - but who knows for how long?

It seems that I need to do this reset thing every morning now, so I
guess it's crashing at least every 24 hours. i have tried unplugging
and replugging the yubikey, it doesn't trigger the problem.
i have tried to figure out what may have happened by looking at the
journald logs, but i can't figure it out. it doesn't clearly mention a
crash.
notice, in the log below, that i reinstalled the package at around Feb
08 10:12:36, which is when things went back to normal. yet before that,
it's unclear what problem there was. you can certainly see a few
instances where systemd started pcscd without it being stopped
first... so there's definitely something going on there.
anything i can do to improve debugging here? note that I don't *need*
pcscd at all. i don't actually know what it is or what it's for. just
want this yubikey to work reliably. :)
