What pinentry version are you using (qt or another one)?
Did you set the GPG_TTY envvar?

pinentry-qt is called, but since being used without a display, I get
the curses dialog in those cases it works.

Did you set the GPG_TTY envvar?

Yes, in my .bashrc.
(but I had the identical problem in the past without GPG_TTY, too)

Still a problem with gnupg-agent 2.0.14-0kk2 and pinentry (or pinentry-qt in
curses mode because of unset $DISPLAY) 0.7.6-0kk1 on Debian lenny:
Does not work on /dev/pts/7, works on /dev/pts/72

Just had the problem on /dev/pts/9 while no problems since 2010-07-29 (because I
usually start mutt in a certain screen window where I made sure that it has a
high-enough tty number)

If in the same terminal (screen window) I export GPG_AGENT_INFO to a different
gpg agent which has access to a $DISPLAY (mutt still without $DISPLAY),
pinentry-qt opens and works fine.

Today I just had the problem again (/dev/pts/9, still same verisons as in T1203 (thomas on Jul 29 2010, 03:35 PM / Roundup))

This looks pretty much like T1311.

Sounds good. I'll test it as soon as we have a kk package for the next release.

STABLE-BRANCH-2-0 344d72b
has the fix. Patch below.

From http://gnupg.org/download/cvs_access.en.html:
the stable 2.0 version (currently version 2.0.16) is known as STABLE-BRANCH-2.0;
the stable 1.4 version of GnuPG (1.4.11) is known under as STABLE-BRANCH-2.0.
I guess I should look at the first of the two :)

Bernhard, can someone provide patched kk binaries?

oops. Website fixed. The branch names are
STABLE-BRANCH-2-0
STABLE-BRANCH-1-4
Note the dashs. We don't use a dot because the names date back to CVS and that
does not allow a dot in the name.

A 2.0.17 will be released soon.

I did not have a chance to test 2.0.17 or the patch yet, but for the archive:
I just have an instance of gpg-agent, which does not allow ttys matching
"/dev/pts/??", i.e. two digits. On three-digit-ttys it works. Maybe the
behaviour depends on the length of tty when the gpg-agent was started first or
something similar.

Anyway, looks like the same problem to me, so no further investigation needed.

Meanwhile even 2.0.18 is out. Closing it.
