[pkg-gnupg-maint] Bug#842015: gnupg: gpg --no-tty freezes when there is no X display

[Vincent Lefevre]

Package: gnupg
Version: 2.1.15-3
Severity: important

Emacs lucid starts:

  /usr/bin/gpg --no-tty --status-fd 1 --yes --enable-progress-filter \
  --command-fd 0 --output /tmp/epg-output9765F4x --decrypt -- <file.gpg>

to decode files, even when there is no X display. This is a bug
since this makes no sense (reported as bug 842012), but the fact
that gpg freezes instead of returning with an error is another
bug...
