epubcheck doesn't complain because this is valid NCX / XML. Therefore: no ERROR 
or WARNING for this issue...

However, I have to admit that a HINT (introduced in v3.0.1) would be 
appropriate to report empty text elements as it is totally clear that the 
element shouldn't be empty...

Actually, websites like Bookbaby reject ebooks with such empty elements, and 
refuse to publish them.  As such, this should at least warrant a warning, or 
hint, yes.
