Provide a minimal init.vim/vimrc with less than 50 lines (Required!)

" git/config/_vimrc_mini
unlet! skip_defaults_vim
source $VIMRUNTIME/defaults.vim

if has('vim_starting')
  set runtimepath+=~/.vimbundles/neobundle.vim
endif

call neobundle#begin(expand('~/.vimbundles'))

let g:neobundle#enable_name_conversion = 1
NeoBundle 'Shougo/deoplete.nvim', {'depends': [
     \ 'roxma/nvim-yarp',
     \ 'roxma/vim-hug-neovim-rpc']}

call neobundle#end()

filetype plugin indent on

let g:deoplete#enable_at_startup = 1

How to reproduce the problem from neovim/Vim startup (Required!)

1. touch hello.txt
2. vim -u git/config/_vimrc_mini -U NONE
3. type i to enter insert mode
4. type ./

Expect: it pops up completion candidates, including hello.txt Actual: it does not, but shows ujihisa/ [F] (Just for your info my current dir is `/home/ujihisa)

I tested with this config as well, but the results were still same.

call deoplete#custom#source('file', 'enable_buffer_path', v:false) " default: v:true

[Shougo]

filename completion is broken. Yes.
