Can't reproduce it either with a slightly earlier version of org (.19)
or latest (.44 - note that I'm ahead of origin/master by 3 commits).

Try evaluating this expression which is the one that gave you the error:

(htmlize-face-size 'default)

I get 113 in my setup, so this looks like an htmlize error. I don't
understand where the nil face (which is indeed invalid) comes from.

Also htmlize-face-size wraps the face-attribute call inside an
(ignore-errors ...)  form, so it should *not* blow up. Are you using
some old outdated htmlize code by any chance?
