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

" Your minimal init.vim/vimrc
set runtimepath+=~/path/to/deoplete.nvim/
let g:deoplete#enable_at_startup = 1

  let g:deoplete#enable_debug = 1
  let g:deoplete#enable_profile = 1
  call deoplete#enable_logging('DEBUG', 'deoplete.log')

The reproduce ways from neovim/Vim starting (Required!)

1. enable debugging and profiling
2. open nvim
3. attempt to enter insert mode and error is thrown.

I'm not an expert in deoplete code but seems that let g:deoplete#_logging is set to an empty dictionary the first time rcpnotify is called. Looking at the if statement seems that this behavior is on purpose, now I'm curious about the logic behind it.

For the moment i have commented that line out to be able to use deoplete with debug logs

I will fix it later.
