bug#21091: 25.0.50; `isearch-done' called before `isearch-update' raises wrong-type-arg error

Dunno whether I'll be able to convince you that this is a bug, but here
Recently someone added `isearch--current-buffer' to isearch.el.
This is initially nil. It is given a string value (buffer name) only in
`isearch-update'. But it is called in `isearch-done' and expected to
have a string value there. If it does not, a wrong-type-arg error is
I have code that defines some Isearch commands that each start out by
calling (isearch-done) - they can be called at top level or from
`isearch-mode-map'. Here is the beginning of one:
(defun foo (arg)
(bar 'isearch-forward arg))
(defun bar (arg)
(setq isearch-success t
(let* ((enable-recursive-minibuffers t)
(setq isearch-filter-predicate ...)
When called at top level, `isearch--current-buffer' is nil, and the
wrong-type arg error is raised.
I can "fix" the problem that was introduced by wrapping the
`isearch-done' call in `ignore-errors'. But I think it would be better
for isearch.el not to assume that `isearch-done' is called after
`isearch-update'. I don't think there is a reason why the two need to
be coupled in that way. Adding variable `isearch--current-buffer' in
the way it was done makes the isearch.el code more fragile than it needs
to be, I think.
Anyway, please consider somehow ensuring that `isearch-done' does not
care whether `isearch--current-buffer' has a string value.
Perhaps one possibility would be something like this - dunno.
(setq isearch--current-buffer nil)
(setq cursor-sensor-inhibit (delq 'isearch cursor-sensor-inhibit))))
Or maybe even:
(when (and isearch--current-buffer
