Hi,

I get an error when I use bookmarks in combination with indexed keywords in chapter/section
like the example below. When I comment out the \placebookmarks, things seem to work.
Is this behavior to be expected or is there a workaround/solution ?

Kind regards
Wim Neimeijer

% Example %
\setupinteraction[state=start]
\placebookmarks[chapter]
\setupinteractionscreen[option=bookmark]

\starttext
\chapter{Affiene connectie en affiene \index{geodeten}geodeten}
\section{Inleiding}
\index{Ruimtetijd} Ruimtetijd is een vierdimensionale differentieerbare vari\"eteit. In de vorige paragrafen hebben we op grond
van het equivalentieprincipe van Einstein een metriek en een metrische connectie op \index{Ruimtetijd} Ruimtetijd ingevoerd.
In deze paragraaf zullen we wat algemener een \index{connectie+affiene}affiene connectie op \index{Ruimtetijd} Ruimtetijd invoeren.
Het zal blijken dat de metrische en de affiene connectie aan elkaar gelijk kunnen zijn.
