[XeTeX] Problem with xgreek

[snvv]

Hello
After last texlive update in debian (sid) I have a rather strange "problem"

All my tex files which include \usepackage{xgreek} don't compile anymore.
If I comment out the \usepackage{xgreek} then it compiles and show correct 
output.

I have no idea why this happens or what problems this may cause in the future.

Any help about this please?

Thank you in advance

Sotiris

PS. if you like try to run the code below with and without xgreek.

\documentclass{article}
\usepackage{fontspec}
\usepackage{xunicode}
\usepackage{xgreek}
\setmainfont[Mapping=tex-text]{Minion Pro} % Minion Pro or whatever
\begin{document}
Α Β Γ Δ α β γ δ ά
\end{document}
