I am getting this error now, too. I have the same situation, using LuaTeX to generate a PDF, trying to process that PDF with GS via the command: 

gs -o $@ -dNoOutputFonts -dColorConversionStrategy=/LeaveColorUnchanged -dEncodeColorImages=false -dEncodeGrayImages=false -dEncodeMonoImages=false -sDEVICE=pdfwrite $<

Denis, did you find a fix?
