I have a journal-supplied .cls file that loads natbib through
\RequirePackage{natbib}. I have created a .layout file for this class
and use this class in lyx. However, when I enable natbib, I get an
error 'LaTeX Error: option clash for package natbib'. The error is
caused by a line
\usepackage[authoryear]{natbib}
