It's not my code. The OP claimed he used the function from the
ranger manual.
I tried that function and got the same error you did. But the
function that I wrote about a year ago based on one in the ranger
man page works fine.
It's not immediately obvious to me what the problem with the OP's
function is, but here's the one I use.

" Vim plugin for using ranger as a file chooser
" File: ranger.vim
" Maintainer: Gary Johnson <garyjohn AT spocom DOT com>
" Last Change: 2011-10-31 16:25:58
" From the ranger(1) man page for ranger-1.5.2:
"
" VIM: File Chooser
" This is a vim function which allows you to use ranger to select a file
" for opening in your current vim session.
"
" fun! RangerChooser()
" silent !ranger --choosefile=/tmp/chosenfile `[ -z '%' ] && echo -n .
|| dirname %`
" if filereadable('/tmp/chosenfile')
" exec 'edit ' . system('cat /tmp/chosenfile')
" call system('rm /tmp/chosenfile')
" endif
" redraw!
" endfun
" map ,r :call RangerChooser()<CR>
"
" That function fails when executed in an empty, unnamed buffer with the
" following messages:
"
" Error detected while processing function RangerChooser:
" line 1:
" E499: Empty file name for '%' or '#', only works with ":p:h": silent
!ranger
" --choosefile=/tmp/chosenfile `[ -z '%' ] && echo -n . || dirname %`
" RangerChooser()
"
" Ranger version 1.4.2 or later is required to run this function. That's when
" the --choosefile option was added.
fun! RangerChooser(...)
let tmpfile = tempname()
if a:0 > 0 && a:1 != ""
let dir = a:1
elseif expand("%")
let dir = "."
else
let dir = expand("%:p:h")
endif
exe 'silent !ranger --choosefile='.tmpfile dir
if filereadable(tmpfile)
exe 'edit' readfile(tmpfile)[0]
call delete(tmpfile)
endif
redraw!
endfun
"map ,r :call RangerChooser()<CR>
