In case this helps anyone else:

In my case, the LuaTeX error resulted from what appears to be a corrupt font cache. I was getting the error: 

> !LuaTeX error: cannot find OpenType font file for reading ()
> ==> Fatal error occurred, no output PDF file produced!
 
The solution was to clean the LuaTeX font cache in my ConTeXt standalone directory. Mine was in:
` ~/context/tex/texmf-cache/luatex-cache/context/<...>/fonts/otf/ `

(The <…> represents a long string of numbers.)

I deleted the .tma and .tmc files in that OTF directory. Upon running ConTeXt again, everything worked fine. [The source of this discovery was http://tex.stackexchange.com/questions/65038/luatex-cannot-find-existing-font ]

I am having the same problem as the OP. I have manually edited the font-otr.lua file as per the patch below, and I deleted the font cache. But all to no avail. I still get:

!LuaTeX error: cannot find OpenType font file for reading ()
 ==> Fatal error occurred, no output PDF file produced!

Is there a solution to this?

Many thanks,

The problem persisted with Courier New, not only Source Sans Pro (SSP).

The font file for Source Sans Pro came directly from the Google's font service.

The SSP (on my machine) works fine in Inkscape.

The exact same font was also working before the ConTeXt upgrade.

Confirmed, it appears to work if you revert to the old loader in
font-lib.mkvi.

i need a better example of what fails then as it works here


The problem seems to be the “filename” field being written to the
cache from the wrong source. Between the old and the new
fontloader, you get the following picture in the “resources”
record:

   +  ["filename"]="Everson_Mono_Bold.ttf",
   -  ["filename"]="/tmp/here-be-fonts/Everson_Mono_Bold.ttf",

The attached patch fixes it for me.
