I accidentally typed C-x C-q while in the Minibuffer (during C-x C-f, for
example) and got some peculiar behavior.  

To get the bug, start emacs, then C-x C-f, type 'asdf', then C-x C-q.

Typing any character at this point gives a message that the minibuffer is
read-only.  This is sensible enough, although somewhat useless.  If a C-g is
executed at this point (i.e., before a second C-x C-q), emacs seems to enter a
slightly bizarre state.

A '%' appears on the mode line before the '('.  It is now possible to get into
the minibuffer using C-x C-o and type into it.  If you hit a return, emacs
complains "No catch for tag: exit, nil".  Hitting space gives "Symbol's
function definition is void: nil".  I have seen odd strings like
"\367\377\363\240" appear in the buffer when typing other characters.  Typing
C-g gives "no recursive edit in progress"

I know of no fix for this other than exiting the editor.
