Hi,
I was getting this error when converting an epub to lrf:
Code:
calibre.ebooks.lrf.pylrs.pylrf.LrfError: page id invalid in toc: Photo Credits
(see below for the complete trace)
I changed the code so that when it finds an invalid pageId/objId when generating the toc, it will just use the previous one instead. Granted, it's not very pretty but a book with a sightly inaccurate toc is better than no book
I tested it and my PRS-505 can paginate the resulting lrf with no problems.
Here's the diff and the full trace of the error. I'm running calibre on Ubuntu 9.10 (calibre version 0.6.13+dfsg-0ubuntu3.1)
Enjoy!
