The \" command in TeX says "You see the next item?  Put
a diaeresis over it."  So it is expecting a plain character,
or possibly a command naming a character.  But } is an "active"
character with a special meaning.

The most likely explanation here is that \" should
*really* be \textquotedbl.  Apparently someone thought
\" in TeX was like \" in a C string, but it never has been.

If you can change that line from
\item |hyperindexformat{\"}....
to	\item |hyperindexformat{\textquotdbl}....
the problem *might* go away.
