That could be part of it. But, in both conversions, the starting point is an AZW3 file. The Kepub Output plugin is largely a wrapper for the Epub Output plugin. It should be doing some setup, running the epub conversion and then doing the kepub specific stuff. That is why I was surprised that the same error didn't happen when converting to epub. I have to go back and look at the code as I remember something didn't work purely from class inheritance. We may have missed something. I'll have to see if I have an AZW3 book with fonts to see how it goes. I the book in question from Kobo. The epub doesn't seem to have any issues.

It does make me wonder if it is a matter of exceptions being caught and handled differently.

@Clio: Can you try the conversion but on the Kepub Output page select 2 for the EPUB version? That might work. I can't think there would be any real advantage in using epub3 over epub2.
