Polyglossia redefines \ttfamily, it adds \def\familytype{tt} to it -
obviously to save the "type" of the font. \familytype is also
redefined by \rmfamily and \sffamily.
But now \ttfamily is no longer robust. You can avoid your problem
with \protect:
\newcommand{\broken}[1]{\index...@{\protect\ttfamily #1}}}
But I think polyglossia should change its definitions and make the
commands robust.
