I didn't at first, but I do now. I saw the hanging behavior both before and
after I installed it.

X11 via startx. I run openbox-session at the end of .xsession.

Yes. Version 222-1.

No.

Yes, gpg-connect-agent on its own hangs. (Because I had masked my systemd units
as a workaround, as mentioned in my other email, I unmasked them to reproduce
the hanging scenario in order to test this.)

Originally 2.1.18-6, and then I upgraded to 2.1.18-7. Same behavior in both
cases.

For a couple of them, I edited ~/.gnupg/gpg-agent.conf. For the others, I put
the generic "pinentry-program /usr/bin/pinentry" in gpg-agent.conf and used
Debian's alternatives to specify the preferred variant. In each case, I re-ran
one of the hanging commands after making the change.

I also tried pinentry-gnome3 just now, because I noticed that it's specifically
mentioned in Debian's gnupg-agent README, but it still hangs.
