I can't reproduce it using 'emacs -Q'. But I can't locate where the bug
is and I haven't tried it in Emacs 24.5. The backtrace is :

Debugger entered--Lisp error: (error "Selecting deleted buffer")

This is what I got using `disassemble`:

byte code:
  doc:   ...
  args: (arg1)
0       save-current-buffer
1       dup
2       set-buffer
3       discard
4       constant  buffer-modified-p
5       call      0
6       constant  t
7       dup
8       varbind   buffer-undo-list
9       varbind   inhibit-read-only
10      constant  t
11      varbind   inhibit-modification-hooks
12      constant  make-byte-code
13      constant  0
14      constant  "\300?\205\b\301\302!\207"
15      constant  vconcat
16      constant  vector
17      stack-ref 5
18      call      1
19      constant  [restore-buffer-modified-p nil]
20      call      2
21      constant  2
22      call      4
23      unwind-protect
24      constant  remove-text-properties
25      point-min
26      point-max
27      constant  (fontified)
28      call      3
29      unbind    4
30      stack-set 1
32      unbind    1
33      return

I have grepped my elpa directory and emacs soruce but found no
clue. This is really annoying and makes me turn off `debug-on-error`. I
tried and failed to disassemble the inner byte code above.

I have found the bug -- it comes from nlinum.el:

(defun nlinum--flush ()
  (nlinum--setup-windows)
  ;; (kill-local-variable 'nlinum--ol-counter)
  (remove-overlays (point-min) (point-max) 'nlinum t)
  (run-with-timer 0 nil
                  (lambda (buf)
                    (with-current-buffer buf
                      (with-silent-modifications
                        ;; FIXME: only remove `fontified' on those parts of the
                        ;; buffer that had an nlinum overlay!
                        (remove-text-properties
                         (point-min) (point-max) '(fontified)))))
                  (current-buffer)))

It seems that when the timer is ran, the (current-buffer) no longer
exists. That buffer may be a temp buffer.

And my init code includes:

  (add-hook 'nlinum-mode-hook
            (lambda ()
              (when nlinum-mode
                (setq nlinum--width
                      (1+ (length (number-to-string
                                   (count-lines (point-min) (point-max))))))
                (nlinum--flush))))

A fix would be:

(defun nlinum--flush ()
  (nlinum--setup-windows)
  ;; (kill-local-variable 'nlinum--ol-counter)
  (remove-overlays (point-min) (point-max) 'nlinum t)
  (run-with-timer 0 nil
                  (lambda (buf)
                    (when (buffer-live-p buf)
                      (with-current-buffer buf
                        (with-silent-modifications
                          ;; FIXME: only remove `fontified' on those parts of the
                          ;; buffer that had an nlinum overlay!
                          (remove-text-properties
                           (point-min) (point-max) '(fontified)))))
                  (current-buffer)))

Perhaps it makes more sense to put that buffer-live-p check in your
nlinum-mode-hook lambda? Actually I wonder why you need to call
nlinum--flush at all? Though I admit I don't really understand the
nlinum code either, e.g. what is the use of (run-with-timer 0 ...),
why not run the thing immediately?

Yes that's another solution. In my memory that code snippet in my init
comes from EmacsWiki.
I will try whether it works tonight (UTC+8 here). I don't understand that
timer too.
In Android for example, that might be intended to wait for the GUI event
loop to update some
controls.

I removed that call in my init code, and the error is gone,
at the price of some display inconsistency which is acceptable.
There is room for improvement in nlinum--flush.

How about this instead:

(defun my-nlinum-mode-hook ()
  (when nlinum-mode
    (setq-local nlinum-format
                (concat "%" (number-to-string
                             (ceiling (log (max 1 (count-lines (point-min)
                                                               (point-max)))
                                           10)))
                        "d"))))
(add-hook 'nlinum-mode-hook #'my-nlinum-mode-hook)

Actually, I think count-lines will be slow on big files, so you may want
to approximate with something like

(defun my-nlinum-mode-hook ()
  (when nlinum-mode
    (setq-local nlinum-format
                (concat "%" (number-to-string
                             (ceiling (log (max 1 (/ (buffer-size) 80)) 10)))
                        "d"))))

I've updated the Emacswiki page with this suggestion, and I'm closing
this bug report.
