As of 2010-05-24 Documentation contains 306 items, including 33 open issues:

err... either someone can't count, or there are other statuses not being displayed.
Not every bug is tagged with a keyword. The lines in the Bug Jar summary don't sum up, they're just glimpses into various interesting bits within Bugzilla.
