[OS X TeX] Spurious bold in lualatex

[Martin Berggren]

Issue in lualatex after updating to MacTeX-2013, or perhaps after latest tlmgr update, not sure. I seem to sometimes erroneously get bold body text. Example:

\documentclass{article}
% !TEX TS-program = lualatex

\usepackage[no-math]{fontspec}
\setmainfont{Adobe Caslon Pro}
\title{Title}
\author{Me}

\usepackage{lipsum}

\begin{document}

\maketitle

\lipsum[1]
\section{Section}

\lipsum[1]
 
\end{document}


The body lipsum text's in bold. The only text not in bold is author's name and date. This does not happen when running xelatex or when switching back to MacTex-2012. 

Cheers,
