After some testing, it's easy to reproduce it by putting a font only in 
TEXMFHOME... (copy fxlr.otf in TEXMFHOME/fonts/opentype/newfont.otf and 
try to load it). This looks like a bug in LuaTeX... this could be 
patched by putting the absolute name in the database for TEXMFHOME, do 
you think it would be a good idea? Can someone confirm the bug so that I 
can bugreport it?

I fixed the behaviour in the last push I made... please tell me if you 
see wrong things in it. Will, I'll try to merge your code soon.

Thank you,
