Yes, I am running as calibre-debug -g; but how do I tell where it is bombing out?

I have added more debug statements:

                    current_book_count += 1
                    book.in_library = None
                    print('checking for uuid ', book.uuid, getattr(book, 'uuid', None))
                    if book.uuid in self.db_book_uuid_cache:
                        print('getattr(book, uuid, None) succeeded: ', uuid)
                        id_ = db_book_uuid_cache[book.uuid]
                        if updateq(id_, book):
                            update_book(id_, book)
                        book.in_library = 'UUID'
                        # ensure that the correct application_id is set
                        book.application_id = id_
                        continue
                    print('getattr(book, uuid, None) failed: ', uuid)

while I see my initial print statement, I should get a succeeded or failed from the subsequent 2 print statements, but see nothing.
