Well, your problem is that header:instrument}} is a valid Scheme
identifier, and \fromproperty apparently just ignores identifiers it
finds undefined. So your \context appears right after
\markup{\fill-line{ where LilyPond has no idea what to do with it.
If you insert spaces a bit more liberally, you will be less likely to
forget them where they are absolutely essential, like after symbols
parsed by the Scheme interpreter.
