[boost] is something seriously wrong with zero_vector?

I noticed that creating a zero_vector with some size, and then iterating
over it produced strange results.  Then I noticed this:
        BOOST_UBLAS_INLINE
        const_iterator begin () const {
            return const_iterator (*this);
        }
        BOOST_UBLAS_INLINE
        const_iterator end () const {
            return const_iterator (*this);
        }

Excuse me?  Doesn't this mean begin() == end() and effectively size is
always zero?
