hebrew, bidi, xelatex, wrong brackets equations

[Uwe Brauer]

Hi

The following minimal example works

\documentclass[12pt]{article}
\usepackage{fontspec}
\usepackage{bidi}
\setmainfont{Arial}
\begin{document}
\setRL
שלום
\begin{equation}
\label{eq:hebrew-math:1}
\int
\end{equation}
\end{document}

but

\documentclass[12pt]{beamer}
\usepackage{fontspec}
\usepackage{bidi}
\setmainfont{Arial}
\setsansfont{Arial}
\begin{document}
\begin{frame}
\setRL
שלום


\begin{equation}
\label{eq:hebrew-math:1}
\int
\end{equation}
\end{frame}
\end{document}

Results in the «wrong» brackets in the equation.

Anybody knows how to solve this?
