After the first C-k, the buffer is deleted, but remains at the
head of the iswitchb list. The second C-k produces an error
"No buffer named <the buffer that was just killed>"
The problem is that iswitchb-make-buflist does not correspond to its
documentation:
"... If DEFAULT is non-nil, and corresponds to an existing buffer,
it is put to the start of the list."
Changing the implementation to match the documentation fixes the bug:

I'm not sure this matters, because if you change the recipe to start:
emacs -Q -f iswitchb-mode \
--eval "(setq read-buffer-function 'iswitchb-read-buffer)"
ie, use iswitchb-mode rather than just adding to minibuffer-setup-hook,
there is no such error. The difference seems to be that C-x b runs
iswitch-buffer in that case rather than switch-buffer.

Ah. iswitchb-mode must have been added after I set up iswitchb
(which I've been using for many years) I was most likely following
this advice which is still in the file header comment block as of emacs
23:
;; Replacement for read-buffer
;; iswitchb-read-buffer has been written to be a drop in replacement
;; for the normal buffer selection routine `read-buffer'. To use
;; iswitch for all buffer selections in Emacs, add:
;; (setq read-buffer-function 'iswitchb-read-buffer)
I'll switch over, but from some experimentation, it seems like using
read-buffer-function no longer
works properly (for example, without the minibuffer-setup-hook,
iswitchb-read-buffer
is even less functional than the default). Perhaps that comment should
be removed?

I don't use iswitchb, but I thought that comment was describing
something extra you can optionally do, beyond what iswitchb-mode (which
is mentioned at the start of the commentary) does by default.
lispref/minibuf.texi still refers to this, so would also need updating
if this is incorrect.

iswitchb is an obsolete package, so I'm closing this bug report.

See my reply to the same statement made for bug #3713.
Where does it say that iswitchb is an obsolete package?
