Description of Problem:
-----------------------
Trouble verfying signed pgp/gpg security alerts from mailing lists.

Steps to reproduce the problem:
-------------------------------
1. subscribe to Debian Security Announcements 
   <debian-security@lists.debian.org>
2. Get a security alert in you your INBOX
3. Evolution sees it as a PGP attachment but not inline I need to save
   it to disk... or change my view
4. With mesg selected change view to "Show E-mail Source"
5. View the message in all it raw glory
6. Change view to "Normal Display"
7. Nice headers again and now you can see the message but it is not checked
   by gnupg. It is show  -----BEGIN PGP SIGNED MESSAGE----- in the message
   and now and the rest of the message but doesn't actually check it.
8. Spend 30 min and submit bug report... :)

Actual Results:
---------------
Just shows just a "Save to disk" option when viewed with "Normal Display"
After changing view to "Show E-mail Source" then back to "Normal Display"
you can read the message inline but it is not checking the signature of
the signed e-mail. You need to view the message while your view is set to
"Show E-mail Source" other wise when you switch back to "Normal Display"
Evolution won't care and just give you the save to disk choice. It has to
be the way pgp/gnupg are being handled since there are different methods
and each mail client seems to do it differently. (thinking about mutt and
pine for example)

Expected Results:
-----------------
Should show the pgp or gnupg inline and check if the signature is valid or
not. 

How often does this happen? 
---------------------------
Every time the following information is in the header...

Content-Type: application/pgp; FORMAT=text; X-ACTION=sign

Now if I sign my own e-mail using Evolution it is handled differently...

Content-Type: multipart/signed; micalg=pgp-sha1;
protocol="application/pgp-signature";

Additional Information:
-----------------------
I see others have mentioned problems with pgp/gpg but following the
duplicate bug reports didn't help me much.
