[pkg-gnupg-maint] Bug#869416: Bug#869416: pinentry-gtk2: fails to request passphrase when importing OpenPGP secret key with Seahorse

[intrigeri]

Hi,

This doesn't seem to be the case:

  # tr '\0' '\n' <  /proc/$(pgrep gpg-agent)/environ | grep -E '^(GPG|DISPLAY|TTY)'
  DISPLAY=:0

I've verified that this gpg-agent is the one running as the desktop
user (/usr/bin/gpg-agent --supervised). This might invalidate the next
steps of this hypothesis i.e.:

I've tried. But then I see no relevant change to gpg-agent's
environment:

  # tr '\0' '\n' <  /proc/$(pgrep gpg-agent)/environ | grep -E '^(GPG|DISPLAY|TTY)'
  DISPLAY=:0

debug-all:

  Aug 11 22:47:34 gpg-agent[2069]: DBG: chan_8 -> OK Pleased to meet you, process 2130
  Aug 11 22:47:34 gpg-agent[2069]: DBG: chan_8 <- RESET

  Aug 11 22:47:34 gpg-agent[2069]: DBG: chan_8 -> OK
  Aug 11 22:47:34 gpg-agent[2069]: DBG: chan_8 <- updatestartuptty
  Aug 11 22:47:34 gpg-agent[2069]: DBG: chan_8 -> OK
  Aug 11 22:47:34 gpg-agent[2069]: DBG: chan_8 <- [eof]

… and then the key importation fails in the exact same way as before:
I'm not asked for the passphrase and the debug-all logs are the same :(

FWIW I've tried both on GNOME/X.Org and GNOME/Wayland (up-to-date sid).

Cheers,
