'kpse.find_file' now can not work in MkIV (beta 2010.06.10 15:24). The
attachment is a minimal example for this. When I compile it, I got the
following error:

 LuaTeX error <main ctx instance>:2: attempt to call field 'find_file'
(a nil value)
stack traceback:
	<main ctx instance>:2: in main chunk.
}inserted text> ...(kpse.find_file ("a", "lua"))

\dodostartluacode ...d \directlua \zerocount {#1}}

l.4 \stopluacode

?
