Re: No VC backend is responsible for

Yes true thanks, I thought Helm could be the issue but it doesn't work.
Actually the problems seems to be my code:
(defun ca-is-version-control-file ()
  "Return nil unless the file is in the git files"
  (if (vc-working-revision (buffer-file-name))
      (auto-revert-mode t)))

(add-hook 'find-file-hook 'ca-is-version-control-file)

Makes sense, it's just a bit surprising because I haven't touched this
code for a long time and it used to work..
Probably checking if the file is under vc using something that is not
vc-workiing-revision would do the trick..
