@davidfor,

I've attached the test source epub and the converted kepub. Hopefully that's enough, but let me know if something's missing.

This is only a guess but I think the problem might have something to do with the cover page file (titlepage.xhtml) being moved out of its text/ sub-directory into the root directory during the kepub conversion. Perhaps the NCX loses track of the move.
