[Bug 1588546] Re: gnupg2 fails, "Line passed to IPC too long"

[Chad Miller]

Okay, the shell I was using to run gpg here didn't have GPG_TTY or
DISPLAY environment variables set, which seems to be the cause of the
problem.

That is a bewildering error message.

Bug description:
  I have a key on a USB-plugged "smart card" in the form of a Yubikey 4
  Nano.

  $ gpg2 --sign noise
  gpg: signing failed: Line passed to IPC too long
  gpg: signing failed: Line passed to IPC too long

  $ echo $?

  In going to gpg-agent.conf and adding debug logging,  Attaching.

  If I kill "scdaemon" and "gpg-agent", they exit, and it has no effect.
  Next run causes the same message.
