Title: fix bug where we were trying to iterate through undefined 'navPoints'

This quick fix works for me, I haven't had a need for navPoints (yet) and am not sure if the problem was due to an invalid epub or a bug earlier in the epub-parser code.

I can send you the offending epub for testing if you let me know your email address.
