I found out that the faulty completion only happens when I start Emacs
with --daemon and then open a frame with emacsclient -c (!?).  If I
start the same Emacs executable without --daemon, completion works in
Gnus as always (so both groups above are offered as completions).  But
completion in Gnus also works in my Emacs build from 2010-09-10 even
with --daemon, so the problem still seems to be at least partly due to
the recent changes.

I've attached two backtraces, the first from the faulty completion with
Emacs running under the daemon, the second from good completion with
Emacs not running under the daemon.  They show relevant differences,
though I don't see anything indicating how those differences arose (much
less what the daemon has to do with it); hope you do.
