[Dfaure]

I fear I triggered an unhandled corner case in the KTE conversion:

Last day, a friend gave me an epub to read, that I put into my Calibre and transfered onto my Kobo using KTE driver in order to get all the bell & whistle from the kepub format.

Then, I noticed that each time I powered on the kobo and resumed reading this book, the reading app couldn't set me back to my last reading position and let me at a chapter start.

So, I decided to open the original epub in the Calibre editor and found that the book was already a kepub, with the kobo.js script and the "koboSpan" spans.

I think that KTE's kepub generation isn't handling very well the case and is building a kepub with self-enclosed "koboSpan" spans or such, which definitely can't be handled as expected by the reader application.
