Okay, working with a munged version of mh-show-msg, I was able to step
through the code a little farther using edebug (The hang-up was the
mh-in-show-buffer macro... I yanked it out, and replaced it with a
switch-to-buffer for now.)

It looks to me like that problem is somewhere inside of

  mh-update-sequences

But... I just noticed a far worse problem.  I can't
change folers.  If I try to do an mh-visit-folder,
I get the complaint:

  mh-folder-size-flist:
    Searching for program:
    no such file or directory, /usr/bin/mu-mh/flist

There is indeed no flist in the mh-progs location: /usr/bin/mu-mh
(which was installed from the ubuntu mailutils-mh package).

So: how can MH-E possibly be expected to work with mailutils?

Consider the claim:

http://www.gnu.org/software/mailutils/

  While being backward compatible with both standard
  mh and nmh, our implementation of MH offers all the
  flexibility and power of GNU Mailutils. It has been
  designed to interoperate flawlessly with GNU Emacs
  MH-E interface. Newer versions of MH-E provide
  support for extended features of GNU Mailutils MH.
