[O] isbn-to-bibtex (from org-ref) fails

[Julien Cubizolles]

I've just tried isbn-to-bibtex with the isbn entry "0201500647" (Feynman
lectures on physics). It fails with:

--8<---------------cut here---------------start------------->8---
funcall-interactively: Wrong type argument: stringp, [((url . 
["http://www.worldcat.org/oclc/67451431?referer=xid";]) (publisher . 
"Addison-Wesley") (form . ["BA"]) (lccn . ["89000433"]) (lang . "eng") (city . 
"Reading, Mass.") (author . "Feynman, Leighton, Sands.") (ed . "8th print.") 
(year . "1996") (isbn . ["0201500647"]) ...)]
--8<---------------cut here---------------end--------------->8---

However, isbn-to-bibtex-lead gets me to the right page with a bibtex
entry ready to be copied.
