I experience the same problem but the above patch doesn't really
help me.  Without the sleeping time, I get failures with signature
checking of incoming emails almost always; with the sleeping time,
it works at least in 20% of the cases.  I increased the time to even
10 seconds but the success rate didn't increase further.  The
behaviour remains probabilistic.

All aspects of GPG interaction -- signature checking, signing and
encrypting -- are affected by this behaviour.

Tschö,
Torsten.

Thanks for further testing.  Well, in that case an essential part of
process-filter might not be executed in 20% of the cases.

Does replacing (sleep-for 0.1) with:

(epg--process-filter (epg-context-process context) "")

change the situation?

It has the same effect as (sleep-for 0.1): It helps, but only
slightly.

Tschö,
Torsten.

Hmm, is your epg-debug output as innocent as the one that the original
reporter provided?

Currently, I suspect that the code in the following clause might be
skipped:

(unless epg-process-filter-running ...)

Can you insert debug-prints in epg-wait-for-completion?  It would be
something like:

(message "epg-process-filter-running: %S" epg-process-filter-running)

And where should I put it exactly?  (I don't speak Lisp.)  I now
wrote

	(unless epg-process-filter-running
	  (message "epg-process-filter-running: %S" epg-process-filter-running)

And then, *Messages* say

epg-process-filter-running: nil

Tschö,
Torsten.

Like this:

(defun epg-wait-for-completion (context)
  "Wait until the `epg-gpg-program' process completes."
  (while (eq (process-status (epg-context-process context)) 'run)
    (accept-process-output (epg-context-process context) 1))
  (message "epg-process-filter-running: %S" epg-process-filter-running) ;; <-
  (sleep-for 0.1)
  (message "epg-process-filter-running: %S" epg-process-filter-running) ;; <-
  )

I get (no matter whether Gnus shows the correct result or not):

epg-process-filter-running: nil [2 times]

Do you get the same result on both successful and failed cases?
(Since I have never been able to reproduce the problem at all, I need
data on failed cases).

Hi,

I'm also exhibiting this behaviour in the following version of Emacs:

GNU Emacs 23.1.50.1 (x86_64-unknown-linux-gnu, GTK+ Version 2.16.5)
 of 2009-08-03 on chateau.d.lf

Following are the last few lines of the " *epg-debug*" buffer:

Like Torsten, I've also got the same string in both cases:

#v+
epg-process-filter-running: nil [12 times]
#v-

Reopening the bug then, awaiting further explanations from Daiki and
