Looks like this is the case here. I removed rails-mode from my .emacs
and that seems to solve the problem for me.

Here are the relevant lines: (untabify-file.el)
(defun untabify-before-write ()
"Strip all trailing whitespaces and untabify buffer before
save."
(when (and (eq this-command 'save-buffer)
(not (find nil
untabify-exclude-list
:if #'(lambda (r)
(typecase r
(string (string-match r (buffer-name)))
(symbol (eq major-mode r)))))))
(save-excursion
(untabify (point-min) (point-max))
(delete-trailing-whitespace))))
(add-hook 'write-file-hooks 'untabify-before-write)
Regards.
