"Cannot read property" on completing python files

[bocajnotnef]

I was working on a python file today and noticed I wasn't getting completions. After googling, I saw that the atom package only has c-family languages enabled by default, so I open settings and add 'python' to the list of languages to autocomplete.

Unfortunately, now when I try to autocomplete I get this error:

TypeError: Cannot read property 'substr' of undefined
    at converters.python (/home/jgf/.atom/packages/you-complete-me/lib/get-completions.coffee:54:50)
    at Array.map (native)
    at convertCompletions (/home/jgf/.atom/packages/you-complete-me/lib/get-completions.coffee:64:15)
    at process._tickCallback (node.js:392:9)

I am running the latest YCMD available, from the master branch, and 0.7.8 for the Atom you-complete-me package.

Any help would be appreciated.

Also, when I open cc files I get this error:

TypeError: Not a buffer
    at TypeError (native)
    at new Hmac (crypto.js:87:16)
    at Object.Hmac (crypto.js:85:12)

    at /home/jgf/.atom/packages/you-complete-me/lib/handler.coffee:165:7

The only change that's happened recently is that the atom you-complete-me package updated.

Something similar is observed with .cpp files, after the recent update:

TypeError: Not a buffer

@bocajnotnef Refer to the solution of Issue #65 . And please inform if it works. Also could you ensure that in the file ycmd/default-settings.json the parameter "hmac" is kept empty.
