Error converting mobi to epub

[szweiner2]

I wanted to report a bug to the support team at Calibre and was forwarded to this site.

I hope I am doing this correctly. I tried to convert Chris Mathews book to epub and got the following conversion error:


calibre, version 0.8.45
ERROR: Conversion Error: <b>Failed</b>: Convert book 1 of 1 (Jack Kennedy: Elusive Hero)

Usually means the book has no line, paragraph or page breaks.
