Linux Libertine Initials break emph

Question

Loading the Linux Libertine Initials font breaks the emph command, even if the font is not used:

\documentclass{scrartcl}                                                        

\usepackage{fontspec}                                                           
\usepackage{xunicode}                                                           
\setmainfont[Mapping=tex-text]{Linux Libertine O}                               
\newfontfamily\lettrinefont{Linux Libertine Initials O}                         

\begin{document}                                                             

This is a test with \emph{emphasis}.                                            


\end{document} 

gives

Is this known? How can it be prevented (other than redefining emph to use Linux Libertine Slanted)?

Answer 1

Other ways to avoid corruption is to define the font with full path in the .tex file or remove the relevant entries in /etc/fonts.

Answer 2

Ok, I had the ttf-linux-libertine package installed, which was conflicting with my local fonts. After removing this package, all works fine!
