Hey, thanks for hanging in there.  I patched minibuffer.el and will
`load-library' the patched version from my .emacs.  That should do it,
I assume.

It's not often that I notice the error (in *Messages*, since the message
itself is fleeting), but I'll try to keep an eye out for the new message
and let you know.  (I added a noticeable STRING arg to the `cl-assert'
form.)
