Works fine here (TL18) as well. 

"Hand-Compiling" fails the first time after changing "use non-TeX fonts" to
"true" but works the second time (when the .aux file is updated).

OTOH, the tests pass here with TL18 (without the advertised fix).
Strange.

Is the output correct without dvips option:

* with TeX fonts,
* with non-TeX fonts?

If yes, we just remove the dvips option, 
if no we should set "PDF (ps2pdf)" as output format.

However, it seems to work in TL18 (the tests pass here).

OTOH, "hand compiling" with non-TeX fonts works only for XeTeX, with LuaTeX,
I get a pop-up window telling me: "The external program lualatex finiished
with an error. It is recommended you fix the cause of the external program's
error (check the logs)." (both with TeX fonts and non-TeX fonts).
"Document>LaTeX Log" is still grey.

When opening LyX from an X-terminal, the output there is

  Unable to read environment locale: exit now.
  support/Systemcall.cpp (291): Systemcall: 'lualatex "Braille.tex"' finished with exit code 1
  Error: LaTeX failed
  ----------------------------------------
  The external program
  lualatex
  finished with an error. It is recommended you fix the cause of the external program's error (check the logs).

This explains why it works fine here (I have LM otf fonts installed
system-wide.)

Done (using DejaVu Sans).
