[ snip diagnosis: summary - Font Lock Mode and Hi-Lock Mode get their
mutual nickers in a twist at the very first C-x w h in a buffer where
font-lock-keywords starts off nil. ]

Here's a proper workaround:  Put the following early on in your .emacs:

   (setq-default font-lock-keywords "\\<\\>")

[The string is a regexp which matches somewhere at both the start and end
of a word, i.e. nowhere at all.]
