Vim: Error detected while processing function vundle#config#bundle[2]..<SNR>33_check_bundle_name:

Question

I'm currently getting the following error when I open up the vim editor.

 Error detected while processing function vundle#config#bundle[2]..<SNR>33_check_bundle_name:
    line    1:
    E121: Undefined variable: s:bundle_names
    E116: Invalid arguments for function has_key(s:bundle_names, a:bundle.name)
    line   11:
    E121: Undefined variable: s:bundle_names
    Press ENTER or type command to continue

From doing research it seems as though this is coming from two conflicting bundles.But is hard to determine from what plugin this error is comign from since it seems I'm only using Vundle. https://github.com/VundleVim/Vundle.vim/issues/682

When I run BundleInstall I get the following file open up:

" Installing plugins to /Users/staguilar/.vim/bundle
Plugin 'VundleVim/Vundle.vim'
Helptags

Not sure if the error is coming from this plugin. Here is my .vimrc file.

let mapleader = " "

set backspace=2   " Backspace deletes like most programs in insert mode
set nobackup
set nowritebackup
set noswapfile    " http://robots.thoughtbot.com/post/18739402579/global-gitignore#comment-458413287

if filereadable(expand("~/.vimrc.bundles"))

" Wrap commit message to 72 characters

if filereadable($HOME . "/.vimrc.local")

and this is the .vimrc.bundles file.

Look in your vimrc.bundles.local file and compare it with your vimrc.bundles file. See if you find any plugin appearing in both files, and if you find it, remove it from either of them.
