[tex-live] (Xe)TeX Live after update: Upright font found, but not italic - Huh?

[Wolfgang Keller]

Hello,

since last week, some update seems to have wrecked something in my TeX
Live installation. The example document (fo testing, you need the
Libertine typeface) below:

%% LyX 2.0.2 created this file.  For more info, see http://www.lyx.org/.
%% Do not edit unless you really know what you are doing.
\documentclass[10pt,ngerman]{scrartcl}
\usepackage[T1]{fontenc}
\usepackage{geometry}
\geometry{verbose,tmargin=3cm,lmargin=5.5cm}
\usepackage{fancyhdr}
\pagestyle{fancy}
\setlength{\parskip}{0pt}
\setlength{\parindent}{0pt}

\makeatletter

}

\makeatother

\usepackage{babel}
\usepackage{xunicode}
\begin{document}
\marginpar{Randnotiz}Text
\end{document}

generates this warning:

LaTeX Warning: Marginpar on page 1 moved.


LaTeX Font Warning: Font shape `EU1/Libertine(0)/m/sl' undefined

LaTeX Font Warning: Some font shapes were not available, defaults

and the attached PDF output. The marginnote text should be
vertically aligned with the body text and in italic.

Could anyone give me a hint what might be broken?

TIA,

Sincerely,

Wolfgang
