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

[intrigeri]

Control: reassign -1 gnupg-agent
Control: found -1 2.1.18-8
Control: found -1 2.1.22-1

Hi again!

NIIBE & I just spent some time debugging this. After some strace &
shell wrapping fun, we identified that for some reason, gpg-agent runs
pinentry-gtk2 without $DISPLAY set in its environment, although it
(gpg-agent) does have $DISPLAY in its own environment according to
/proc/$(pgrep gpg-agent)/environ.

Pointing pinentry-program to a shell wrapper that exports DISPLAY=:0
before exec'ing pinentry-gtk-2 works around the problem.

So I'm reassigning this to gnupg-agent, where the root cause of the
problem seems to live.

Thanks a lot :)
