Error detected after moving a file

[c10b10]

I always get a similiar error:

after I rename a file (even when the file isn't open in any buffer). These are my NT vimrc settings:

    augroup ps_nerdtree
        au!

        au Filetype nerdtree setlocal nolist
        " au Filetype nerdtree nnoremap <buffer> K :q<cr>
    augroup END

    let NERDTreeHighlightCursorline = 1
    let NERDTreeIgnore = ['\~$', '.git$[[dir]]', '.DS_Store', '.*\.pyc$',
                        \ 'pip-log\.txt$', 'whoosh_index', 'xapian_index', '.*.pid',
                        \ 'monitor.py', '.*-fixtures-.*.json', '.*\.o$', 'db.db',
                        \ 'tags.bak']
    let NERDTreeShowHidden = 1
    let NERDTreeMinimalUI = 1
    let NERDTreeDirArrows = 1
    let NERDChristmasTree = 1
    let NERDTreeChDirMode = 1
    let NERDTreeMapJumpFirstChild = 'gK'
    let NERDTreeBookmarksFile = expand('~/some/path')
    let NERDTreeShowLineNumbers=1
    let g:NERDTreeWinPos = "left"
    let g:NERDTreeWinSize = 35

Is this a bug?

I actually ran into this as well just today.

This seems to be caused by the fact that the folder specified to hold the bookmarks file is not present. In @c10b10 's screenshot, it is /Users/c10b10/bin/dotfiles/vim/nt that doesn't exist. I can only assume that the vimrc text was edited to be ~/some/path after the screenshot was taken. If you create the folder first, then this error goes away, but it is a workaround, and we can consider this to be a bug.
