No the running head is not in italic, it uses \slshape. And this is
the source of the problem: A current fontspec or your xltxtra
redefines \em/\emph so that it switches to upshape only if the
current shape is \itshape.
\listfiles
\documentclass{book}
\usepackage{fontspec} %version v2.0b, loads fontspec-patches
\begin{document}
{\slshape blub \emph{bla}} %slshape + itshape
{\itshape blubb \emph{blabla}} %itshape + upshape
\end{document}
