Glad to hear it causes no long-term problems. And that the issue is not
actually present in a formal release.

It was only ever in subversion between 0.6.2 and 0.6.3, there were no
interim releases. However, I did notice one thing and forgot to bring
it up (a cardinal error, I didn't write it down). In order to set the
library to nil, you have the following lines in library.rb (434 & 435)
      temp_book=book
      temp_book.library=nil
And then you write out temp_book. That first line there only copies the
*reference*, you probably wanted temp_book=book.dup to copy the object.
I don't know what effect setting a book's library to nil will have in
the grander scheme of things. In reality, I think book.library is only
used by the ReadingList application.
