bug#18438: 24.4.50; assertion failed in bidi.c

[Aidan Gauland]

There does not appear to be any pattern to this.  Sometimes it happens
when I'm typing in an ERC buffer; sometimes it happens when I'm typing
in a python-mode buffer; sometimes it happens when I'm typing in the
minibuffer.  I don't think it has happened when I was *not* sending
keystrokes to Emacs, but nothing else is apparently common between the
situations in which this happens.
