I tested a bit with various files and it seems ok. But -- as the question on tex.sx shows -- the bug didn't always lead to errors but could simply produce faulty output and it is not so easy to check if somewhere an "and" or a comma is missing. If one loads the new xkeyval v2.6c before keyval the error is still there. So xkeyval needs a patch too. -- Ulrike Fischer http://www.troubleshooting-tex.de/
