Problems with PGG and method=pgp mode=sign

Problems with PGG and method=pgp mode=sign

-----BEGIN PGP SIGNED MESSAGE-----


None of my messages generated with the above settings verifies with
GnuPG.  Sometimes I see some 8bit-fuzz at the end of the PGP signature
being generated, sometimes it looks like this:

Sometimes it looks OK but nevertheless it doesn't verify.

Lets see, what this message will look like :)

Yes, it failed as well.  Could whoever checked in pgg look into this?

Probably a silly question but should gnus, with pgg from CVS about
an hour ago, show the verification state?

For me it just shows as a 'normal' message as though it was not
signed.

Press `W s'.  If you want buttons permanently, try something like: 

(setq gnus-buttonized-mime-types '("multipart/encrypted" "multipart/signed"))

If you want verification/decryption to happen automatically, frob
mm-{verify,decrypt}-option.

'W s' does nothing at all on that particular message (or earlier ones
in the thread.) Looking at the headers, the message is not
'multipart/*' (it is text/plain) and has an 'inline' signature. Gnus
normally displays and verifies PGP/MIME signatures as I have
mm-verify-option set to 'known'.

W s (gnus-summary-force-verify-and-decrypt) shows me

  [[PGP Signed Part:Failed]

but C-c / v (mc-verify) says "Good signature..."

Perhaps the W s verify removes the quoted printible encoding while
C-c / v  works on the raw file.
                 
On the command line 'gpg --verify' verifies the raw file.

Interesting.

It may.  I noticed that your signature verified fine with W s.

That's reassuring.  Sounds like a bug.

Not for me.  But your mail failed.  Hm.  Maybe due to Emacs CVS?  I'll
upgrade and try again.

Without MULE, probably.  There is some known problems with non-mule
emacsen.  I have proposed this patch, does it help you get rid of the
^M's?  Or do you have other problems too?

This seems unrelated to PGG to me -- if you remove the MML tag for
PGP, can you post?  Hm.  If you C-u preview the mail, does it contain
all headers?  Perhaps the code somehow alters the original headers.

No, I tried this.

Since you fixed the PGG related problem, I cannot reproduce this
anymore.  Thanks anyway :-)
