Since it's still opened in the bug tracker, I'm writing to you.

I think that this is the issue of pinentry program.  I couldn't
reproduce it in my environment of today, I checkd the pinentry commit
log.

I believe that the particular issue was handled by this commit.
So, I think it was fixed already (in 0.9.0 or later).

        Check if we are on tty before initializing curses.

        * pinentry/pinentry-curses.c (dialog_run): Check stant stdin and stout
        are connected to ttys.

        When we did not have a ttyname we just used stdin/out without checking
        if it's a proper TTY or a pipe. In some cases this can cause endless
        loop or escape seqeunces on the terminal.

        This commit changes behaviour so that if stdin/out is not tty and no
        ttyname is specified we error-out with errno set to ENOTTY

Pinentry is under active development now.  Please try newer version.
