Thank you very much for taking the time to try this on your devices and to play with the file, DNSB.
Knowing that you were only able to reproduce this on a modded device made me reflect on what changes I've been making to mine. At first I thought none, as no patches are installed on it, but then I remembered I had applied a custom English hyphenation dictionary to it. Replaced it again with a smaller file and now this book (and a couple of others which were giving the same issue) are not crashing my Kobo anymore.
