Subject: 23.0.91; emacs-snapshot20090308: epa can not save .gpg buffer
Date: Tue, 10 Mar 2009 21:43:58 +0100

I opened a buffer, named testing.gpg. I entered some text and tried 
to save it to disk. I got the message:
   Saving file /home/username/testing.gpg...
   byte-code: Opening output file: integer-or-marker-p, nil
The buffer was not saved.

I tried several setups: 
(require 'epa-setup) (require 'epa-file) (epa-file-enable)
(require 'epa) (epa-file-enable)
and "emacs -Q".

Nothing worked.

Output "M-x toggle-debug-on-error":

Debugger entered--Lisp error: (file-error "Opening output file" integer-or-marker-p nil)
  signal(file-error ("Opening output file" integer-or-marker-p nil))

I can't reproduce this bug.

Could you please go to epa-file.el, and do M-x eval buffer RET, then
trigger the bug again?  That might provide a more informative Lisp
backtrace.  Thanks.

Did so. This is from my running emacs, but I verified the problem is
also when emacs-snapshot is started -Q.
I would love to do more, but I can't. :(

Perhaps you have a separate `easypg' package installed, which currently
does not contain the fix for Bug#545:
http://debbugs.gnu.org/cgi/bugreport.cgi?bug=545

If so, you can just remove that package since emacs-snapshot includes
easypg.
