This patch does do the job; The bug does not happen with this patch.

Two other things, though:

1) In working on this bug, I noticed that the mode line on the GUI frame
   was not correctly indicating the frame name. Should I file that as a
   separate bug? Add it to some other current outstanding bug? Let it
   stand as part of this report?

2) Likewise, for more than two years I've intermittently been having a
   'grave' emacs bug that I never reported on this list because I
   couldn't ever figure out how to reproduce it. In working on this bug,
   I seem to have figured out the problem (but not a solution):

   2.1) Whenever a minibuffer is active in one frame, the other windows
        on that frame are navigable and operable. However, all elements
        of all other frames are completely frozen.

   2.2) This most commonly seems to have been happening to me when
        composing an email message using mutt, which I have configured
        to use emacsclient as its editor.

   2.3) Up until now, my work-around has been to `pkill emacsclient` and
        restart the client (this doesn't cause any data loss, since all
        data is on the server).
