[XeTeX] Missing Math Accents

[Herbert Schulz]

Howdy,

I just downloaded and installed 0.995 and am no longer getting math  
accents. I'm using the amsmath package and

\usepackage{fontspec,xunicode,xltxtra}
\defaultfontfeatures{Mapping=tex-text}
\setromanfont[Scale=1.08]{Minion Pro}
\setsansfont[Scale=MatchLowercase]{Myriad Pro}
\setmonofont[Scale=MatchLowercase]{Verdana}

and then the equation

\begin{equation}
\mathbf{l} =  \mathbf{x} \wedge (\dot{r} \hat{\mathbf{x}} + r \dot 
{\hat{\mathbf{x}}}) = r^{2}\hat{\mathbf{x}}\dot{\hat{\mathbf{x}}}
\label{eq:l}
\end{equation}

has no accents any more. :-(

Good Luck,
