After doing a factory reset (but still running 4.31) I uploaded just 5 books (which I've uploaded before and so I think they're fine) and didn't get any errors. Libra 2 is behaving ok with these 5 books.

I'm not planning to mess around with reverting firmware or installing patches, but if you're sure the kobotouch_extended error relates to a book (and could not be caused by a corrupted database), I can try uploading some recent additions to my library, to try and narrow it down.
The error is some code doing cleanup of the book code. It happens before attempting to send a particular book to the device. It could be related to sending a lot of books in one go, it could be something unusual in a particular book.

Are you using a 32bit or 64bit build of calibre? It could be a memory issue if you are using a 32bit version and very big book.
