Thanks for checking, and for the fix. I have applied the changes. I have also fixed the open bugs: a small typo, and a consistency check. The third open bug was exactly the error you got. I attach the new release candidates. bcb0b708d2ec19c625c6ab3961496948 target/nurbs-1.4.3.tar.gz 06c68bf493c154dcf8d77d82e225fa3c target/nurbs-html.tar.gz
