Here's a smaller one:

\documentclass{article}
\usepackage{polyglossia}
\usepackage{fontspec}
\setmainfont{TeX Gyre Pagella}
\begin{document}
\setbox0\hbox{\textsc{Vertical}}%
\unhbox0\par
\end{document}

It seems to boil down to this recipe:
 - load polyglossia
 - load fontspec
 - \setmainfont
 - \setbox with \textsc (also depends what is in \textsc)
 - \unhbox
 - BOOM!

Simply moving polyglossia after \setmainfont seems to work (no idea how
well though).
