I have a different problem, which is that on one imap server, but not
the other, articles in INBOX show up again after being deleted.  I work
around this by 'rm -rf ~/News/agent'.  Both setups are NetBSD/i386
4_STABLE with recent dovecot 1.0.x, emacs 22.1, and gnus trunk.  I
also access both servers with Apple Mail.app, iphone, and thunderbird.

So, I think your problem might be that the local gnus has a cache about
metadata for the article and is showing it, but really you've deleted
it, so when you select it fetching fails.

I think that caching information about imap is basically too dnagerous,
at least without somehow validating it.  I've tried to turn it off, but
haven't managed to:

(setq gnus-secondary-select-methods
      '((nnimap "[redacted]"
		(nnimap-address "[redacted]")
		(nnimap-port 993)
		(nnimap-stream ssl)
		(nnimap-authenticator login)
		(nnir-search-engine imap)
		(gnus-agent-cache nil)
		)))
