Summary: can't "q" after "Fu"

Initial Comment:
if i "emacs -q" (no init file), then "Fr" (to give me a message to play
with), then "o" (to move that message to a folder), then (THIS IS KEY)
"Fu" and reply "yes" (to undo all pending changes in the current
folder),

then, if i say "q", i get "mh-quit: Wrong type argument: consp, nil"
(after colon in minibuffer; full message in *Messages*).
