[XeTeX] Wrong placement of indices of \sum in displayed formulae when using Neo Euler

Hello,
I am having a problem with mathematical typesetting under XeLaTeX:
In a formula like
\[ \sum_{i=1}^n \ldots\]
The indices i=1 and n appear too close to the Sigma. Moreover, they do not stand centrally above and below the Sigma.
The following is a minimal example illustrating the problem:
\documentclass{article}
\usepackage{fontspec}
\setmainfont{CMU Serif}
\usepackage[math-style=upright,vargreek-shape=TeX]{unicode-math}
\setmathfont{Neo Euler}
\begin{document}
\[ \sum_{i=1}^n\]
\end{document}
I first thought that it may be a problem with the font Neo Euler, but Khaled pointed out that the problem does not occur under LuaLaTeX.
I hope that somebody from the forum can help me to overcome this problem.
I should add that I am working with MacTeX 2010 with the newest updates under OSX Version 10.6.4.
Thanks,
Chrstian
