This happens due to a race condition between FuzzyProvider.onChanged and FuzzyProvider.lastTypedWord.

https://github.com/saschagehlich/autocomplete-plus/blob/master/lib/fuzzy-provider.coffee#L61-L63

if e.newText in ["\n", " "]
    newLine = e.newText is "\n"
    @addLastWordToList newLine

https://github.com/saschagehlich/autocomplete-plus/blob/master/lib/fuzzy-provider.coffee#L68-L69

addLastWordToList: (newLine) ->
    lastWord = @lastTypedWord newLine

https://github.com/saschagehlich/autocomplete-plus/blob/master/lib/fuzzy-provider.coffee#L81-L87

lastTypedWord: (newLine) ->
    selectionRange = @editor.getSelection().getBufferRange()
        {row} = selectionRange.start

        # The user pressed enter, check previous line
        if newLine
            row--

If @editor.getSelection().getBufferRange() has not yet advanced to the next line, row will be -1, leading to TypeError: Cannot read property 'length' of undefined.
