I believe this is a compatibility issue with htmlize.el and the most
recent versions of Emacs.  I had a similar issue, and made a change to
my copy of htmlize.el following a suggestion from a mailing list (I
don't remember what change or what list) and the line you posted above
is now working for me.

I'm attaching my copy of htmlize.el, hopefully it will fix your problem.
