Severity: to important given that this causes most of the email in Gnus
to not be available (latest Debian emacs-snapshot package, version
20110323-1), for example with a post on debian-devel@lists.d.o:

FWIW, re-loading mm-util.el.gz (from Debian emacs-snapshot-el) solves it:

  (load-file "/usr/share/emacs/24.0.50/lisp/gnus/mm-util.el.gz")

I guess because mm-decode requires mm-bodies which requires mm-util...
