Crash on named page

[7596ff]

I'm having a crash with a few different books, but this one is reproducible. When I highlight a text selection and annotate it, trying to go to the next page crashes the application. Here is my crash.log:

I can't reproduce. Could you provide the entry in .metadata.json associated with this book?

Okay, the issue resides in trying to move to a named page. The page that the reader display shows is 45, but since pages are 0-indexed in code, it is 44. Going to the next page (45 in the code, 46 logically) is the crash. The same thing happens when going from logical page 47 to 46.
