I have been using gnus and epg for a while, and things have generally
worked well.  I just tried to send a message with the following from
machine with up-to-date gnus cvs and epg cvs and emacs 22.1.1 (plus
NetBSD/4 on i386).  Bogusly quoted to avoid interpretation by this gnus:

  <&sharp;secure method=pgpmime mode=sign>

When trying to send, I was prompted for passphrase (no agent running)
and then it failed with:

byte-code: Wrong number of arguments: #[(context operation) "¢Â=„ ÄÅD\"ˆAÆ	I‡" [context operation epg-context signal wrong-type-argument epg-context-p 14] 4 ("/usr/pkg/share/emacs/site-lisp/epg/epg.elc" . 13659)], 1


After nuking the .elc files and restarting emacs and trying again with

  <&sharp;secure method=pgpmime mode=sign>

I get the more friendly:

byte-code: Wrong number of arguments: (lambda (context operation) "Set the name of the current cryptographic operation." (unless (eq (car-safe context) (quote epg-context)) (signal (quote wrong-type-argument) (list (quote epg-context-p) context))) (aset (cdr context) 14 operation)), 1


Has anyone else seen this?
