[NTG-context] Problem with rfc4180splitter in last beta?

Hi Hans.
Once again. It occurred to me to send a minimum Hans's example. When I 
compile with new beta version are the results the same for header and 
noheader versions, while a compilation of TL 2014 Contex proceeds 
differently.

% csvfile.txt content:
% first,second,third,fourth
% 1,"2","3","4"
% "a","b","c","d"
% "foo","bar""baz","boogie","xyzzy"

\startluacode

local mycsvsplitter = utilities.parsers.rfc4180splitter()
local crap = io.loaddata("csvfile.txt")

local list, names = mycsvsplitter(crap,true)   inspect(list) inspect(names)
-- local list, names = mycsvsplitter(crap)        inspect(list) 
inspect(names)

context.starttabulate { "|l|r|" }
for i=1,#list do
     local l = list[i]
     context.NC() context(l[1])
     context.NC() context(l[3])
     context.NC()
     context.NR()
end
context.stoptabulate()
