That's a quite ironic bug. slides is doing what Will likes to do
too: It handles \textit and \textsl identically by setting
\def\itdefault{sl}
\def\sldefault{sl}
Now when you are using \textsl, fontspec doesn't find
EU1/Arial(0)/m/\sldefault and tries
EU1/Arial(0)/m/\ifdefault instead and ends in a loop:
LaTeX Font Info: Font shape `EU1/Arial(0)/m/sl' in size <12> not
available
Font shape `EU1/Arial(0)/m/sl' tried instead on input line
You can reproduce the problem with other classes too:
\documentclass[12pt]{article}
\def\itdefault{sl}
\usepackage{fontspec}
\setmainfont{Arial}
\begin{document}
\errorcontextlines=100
hi \textsl{hello}
\end{document}
