This error message is related to DISPLAY or GPG_TTY.

I guess that pinentry is invoked with no DISPLAY and no GPG_TTY.  It
failed to open window, and then, it failed at isatty (3), then return
ENOTTY (its error string: "Inappropriate ioctl for device").

When DISPLAY is there for gpgme, gpgme sends "OPTION display=:1" to
gpg-agent.

Does Seahorse have DISPLAY env var?

I think that gpg has DISPLAY env var under GNOME Terminal.
