I am experiencing strange problems with ConTeXt IV / LuaTeX. I have some hebrew words which continues to throw following errors: error: /usr/share/texmf/tex/context/base/font-otn.lua:1809: attempt to index local 'chainlookup' (a nil value) My tools are from Adam Reviczky's Ubuntu PPAs (links can be found here) and I just updated them to make sure I have the newest set.
Here is my test file. Cardo font is available from here. Unfortunately the link for 0.99 version was dead so there may be different errors with newer version. I also tried with Ezra SIL font which is available for Ubuntu as ttf-sil-ezra package and actually got more errors. With older standalone installation of ConTeXt IV this works.
Any advice?
