[NTG-context] font error in float placement?

[NTG-context] font error in float placement?

[Henning Hraban Ramm]

(LMTX, latest beta with self-compiled binary on OSX-intel.)

With my book, I run into an Lua error while placing a sidefloat.
If I comment \externalfigure or replace the image with a different one, 
the error disappears.

I can’t reproduce it in a minimal example, so I guess it depends on the 
current surroundings.

Since it points to some font handling and the figure is a PDF containing 
fonts, I guess it might depend on the new handling of fonts in PDFs, but 
it doesn’t change regardless of 
\setupexternalfigures[compact=preset:merge] or other settings.

Here’s the image:

(In a simple document it works.)

I found a workaround: I opened the file with Inkscape and converted 
everything in curves. The PDF is even smaller now, and it proves that 
the problem was with the fonts. Saving it in Acrobat Pro didn’t help.

BTW the "compact" settings didn’t change anything for my big songbook 
(hundreds of note line PDFs with included fonts); I’m not sure about the 
code examples in my ConTeXt book.

I found more graphics (PDFs with included fonts) that triggered the 
error, one of them a LilyPond example that was no problem in the songbook.
Something in my ConTeXt book setup causes a different handling of these 
externalfigures – but a small example with the same environments worked.

Whenever I've had odd results like this it's been the result of an accumulation of 'small' errors. For example, I once had a missing } in a macro in an environment file. For whatever reason, it didn't trigger an immediate end to the compilation run and a product with one or two components (using that environment) didn't trigger odd behaviour. But once all components were included then the odd behaviours started happening.
