Version: 2011.20120510-1
Severity: important
File: /usr/bin/xetex

Dear Maintainer,

After recent update of texlive, xetex fails to compile all my documents.
I've tracked the problem to the following minimal example:

- 8< - (xetex-bug.tex)
\documentclass[12pt]{article}

\usepackage{polyglossia}
\setdefaultlanguage{russian}

% NOTE: without defaultfontfeatures it works
\defaultfontfeatures{Scale=MatchLowercase}

\setmainfont{Linux Libertine O}
%\setsansfont{Linux Biolinum O}
%\setmonofont[HyphenChar=None]{DejaVu Sans Mono}


\begin{document}
Привет Мир!
\end{document}
- 8< -

on which xelatex fails this way:

NOTE that with \defaultfontfeatures commented out it works.

I've searched the web a bit, and it seems the bug, at least a very
similiar one, was already reported upstream in 2010:

http://tug.org/pipermail/tex-live/2...27549.html
http://tug.org/pipermail/tex-live/2...27582.html

It used to work with TeXLive 2009 in testing.


Thanks beforehand,
Kirill
