Recently mhchem and beamer have stopped working well together, especially in the equation environments. When a chemical equation is placed in an equation environment, I get the following error:

ERROR: Undefined control sequence.

--- TeX said ---

\getanddefine@fonts ...p@font \let \textfont@name

\font@name \xdef \font@nam...

l.21 \end{frame}

A minimal example is:

\documentclass{beamer}

\usepackage[latin1]{inputenc}

\usepackage[T1]{fontenc}

\usepackage[version=3, arrows=pgf]{mhchem}

\newcommand*{\ra}[1]{\ensuremath{\dot{\mathsf{#1}}}}

\usetheme{Goettingen}

\begin{document}

\begin{frame}

\frametitle{S-Nitrosylation}

\begin{itemize}

\item{On Cys-residues: \ce{R-SH + $\ra N$O <=> R-S-$\ra N$-OH}}

\item{Additional pathway for \ce{$\ra N$O} regulation besides

cGMP-dependent kinase}

\end{itemize}

\begin{eqnarray}

\label{eq:1}

\cee{R-SH + $\ra N$O &<=>& R-S-$\ra N$-OH}

\end{eqnarray}

\end{frame}

\end{document}

Any thoughts?

I don't get that error. Instead, I get a different one:

To find your error, look more carefully at your log file and find out line 21 of what file is causing the error.

These are all the files my system accessed while processing (command \listfiles before \begin{document}). You might want to check what versions you are using (mine are TeX Live 2009 under Ubuntu).

The error appeared when the mhchem was upgraded from the 6/10 version
to the 5/11 version. I was able to find a copy of the 5/11 version
and the error disappeared. When I have a little time (I have a
pressing document to finish), I'll take a closer look.
