The trick is in mult-ini.tex, which redefines dosetvalue & co
to support the multilingual interface; this is a problem when
you want to get raw (unconverted) keyword/value sets, which is
why it fails. ConTeXt used to have "raw" version of the
do..value commands, but they disappeared at one point. Yes,
they should be re-introduced.
