[Kepler-Project] difference in luafilesystem between 1.4.2 and 1.5?

[Chad Phillips -- Apartment Lines]

i'm having problems getting code i wrote using luafilesystem-1.4.2 to work 
properly with luafilesystem-1.5.0.

here's the code in question:

    require "lfs"
    local path = script_path .. jester.conf.help_path
    print(lfs.currentdir())
    print(path)
    local dir = lfs.dir(path)
    local file_list = {}
    for file in dir do
      -- Exclude directory references and hidden files.
      if not string.match(file, "^%..*") then
        table.insert(file_list, file)
      end
    end

here's the error message:

colossus$/sw/etc/luarocks: jhelp
/sw/bin/lua51: ./jester/help.lua:70: bad argument #1 to '(for generator)' 
(directory metatable expected, got nil)
stack traceback:
        [C]: in function '(for generator)'
        ./jester/help.lua:70: in function <./jester/help.lua:29>
        (tail call): ?
        [C]: in function 'plain_require'
        /sw/share/lua/5.1/luarocks/require.lua:256: in function 'require'
        jester/jester.lua:2: in main chunk
        [C]: ?

those print() lines in the code were added for debugging, and return the same 
exact thing using both 1.4.2 and 1.5.0:
/usr/local/freeswitch/scripts
jester/help

does 1.5.0 have a problem opening directories from a relative path from the 
current directory?  that's what it seems like...

any ideas?

chad
