I've seen a couple of similar reports recently:

Katsumi Yamaoka changed some w3m related stuff recently.  Maybe he has
an idea.  [ Copying ding@gnus ]

This is in the FAQ:

I know that problem, sorry.  I'll make an effort to make it work
with old w3m.  At any rate, the change I made is required to
display non-ASCII text including Latin-1.

BTW, you can customize the `mm-text-html-renderer' variable to
the value other than `w3m-standalone'.

The problem is that I use the default value for
mm-discouraged-alternatives (wich is also the value indicated in the
above FAQ entry), so Gnus should not try to render HTML...

More details about the above, the error message seems to be this:
gnus-agent-read-agentview no longer supports version %d.  Stop gnus,\
 manually evaluate gnus-agent-convert-to-compressed-agentview, then
 restart gnus.

But how to "manually evaluate gnus-agent-convert-to-compressed-agentview"  is
not obvious, that function takes one (undocumented) parameter and the
user cannot guess what that parameter might be. 
Another thing is that gnus-agent-convert-to-compressed-agentview is
not autoloaded, or loaded by default so for some users would be
difficult to even find the function...

The default value is nil (see mm-decode.el), but the FAQ entry
suggests to add "text/html" and "text/richtext".

Maybe you misinterpreted the text ``[...] then the value of this
variable should be set to: ("text/html" "text/richtext")'' in the doc
string as the default value?

Yep, you are right. I shouldn't have been looking at that so late at
night, sorry... 

Is this something new(ish)? I had the impression that by default Gnus
would display by default the text/plain alternative iff a message
contained text/plain and text/html alternatives.

No, there were only documentation additions in 2005.  From vc-annotate
(sorry for the long lines):

5.65         (larsi    04-Dec-99): (defcustom mm-discouraged-alternatives nil
5.46         (larsi    04-Jul-99):   "List of MIME types that are discouraged when viewing multipart/alternative.
5.42         (larsi    17-Apr-99): Viewing agents are supposed to view the last possible part of a message,
5.42         (larsi    17-Apr-99): as that is supposed to be the richest.  However, users may prefer other
5.42         (larsi    17-Apr-99): types instead, and this list says what types are most unwanted.  If,
5.77         (fx       27-Apr-00): for instance, text/html parts are very unwanted, and text/richtext are
5.42         (larsi    17-Apr-99): somewhat unwanted, then the value of this variable should be set
5.42         (larsi    17-Apr-99): to:
5.42         (larsi    17-Apr-99): 
7.33         (yamaoka  12-Dec-05):  (\"text/html\" \"text/richtext\")
7.33         (yamaoka  12-Dec-05): 
7.33         (yamaoka  12-Dec-05): Adding \"image/.*\" might also be useful.  Spammers use it as the
7.33         (yamaoka  12-Dec-05): prefered part of multipart/alternative messages.  See also
7.33         (yamaoka  12-Dec-05): `gnus-buttonized-mime-types', to which adding \"multipart/alternative\"
7.33         (yamaoka  12-Dec-05): enables you to choose manually one of two types those mails include."
7.33         (yamaoka  12-Dec-05):   :type '(repeat regexp) ;; See `mm-preferred-alternative-precedence'.
5.65         (larsi    04-Dec-99):   :group 'mime-display)

Well, then something else is involved here. 
I just tried with Gnus from emacs-21.4 and for that version the
text/plain alternative is shown, for emacs CVS the text/html version
of the same message is shown. For both emacs versions
mm-discouraged-alternatives was not changed from the default.
