This report was handled in a different forum, and debbugs wasn't Cc'd,
apparently.  So I'm just closing this report.

Subject: 24.0.50; Gnus nnimap broken
Date: Sat, 27 Nov 2010 01:10:21 +0800

I updated from bzr for the first time in a few months today, and
immediately ran into problems with Gnus.

My Gnus related variables are:

 '(gnus-select-method (quote (nnimap "localhost")))
 '(gnus-sieve-crosspost nil)
 '(gnus-sieve-file "~/.sieve.d/Gnus.sieve")

everything else is set to defaults.

Upon starting Gnus, some of my groups are showing unread articles in the
summary buffer, including groups which I only manually move articles
into, and which I have not touched for months.  After entering these
groups, I see some old articles that I have ticked, and some lines
saying that an article has not been downloaded (I have fixed the problem
now, and I did not have the foresight to note down the exact text).  It
seems gnus-agent (which I never explicitly enabled, but have had problems
with in past upgrades after it was enabled by default) is out of sync
with the server, and deleting the ~/News/agent directory fixed the
problem.

Now when I start Gnus, I get the message 

nnimap (localhost) open error: 'Unable to contact localhost:imaps via
ssl'.  Continue?

I answer 'y', expecting Gnus to continue using imap, as I configured it,
but get the following messages:

Reading /home/jasonr/.newsrc.eld...
Opening nnimap server on localhost...
Denied server nnimap+localhost
Opening nnimap server on localhost...failed: Unable to contact
localhost:imaps via ssl

This is a terrible user experience.  Trying SSL first is a good feature,
but if it fails, Gnus should fall back to using plain imap as the user
has configured.  It isn't even obvious to me what variable I have to set
to access plain imap anymore.

Following this, I configured Gnus to use imaps (which I have configured on a
non-standard port to get through certain firewalls but never bothered to
use before on localhost), and now run into a third problem.  Upon
logging in, I am prompted to add my login credentials to
~/.authinfo.gpg.  This brings up a confusing buffer asking me to mark a
public key, which I have discovered by trial and error only works if I
select no public keys so it falls back on symetric encryption.  After
entering an encryption password twice, I was able to read my mail at
last.

But my problems aren't over yet. When I quit Gnus and start it again,
my encryption password for authinfo.gpg doesn't appear to work.
Actually, it is working, because if I enter a different password, it
fails immediately, whereas if I enter the correct password it loops
forever asking for my password (maybe not forever, but my patience for
finding out is limited).

Using C-x C-f to find ~/.authinfo.gpg works after entering the password
once, the the problem seems to be particular to the way Gnus is opening
the file, not a general problem with file decryption.

The messages from this failure are below.
