Hi,

in emacs -Q, eval

(global-set-key [f11] (lambda () (interactive) (make-frame)))

then C-h k <f11> gives you

describe-key: Wrong type argument: symbolp, (lambda nil (interactive)
(make-frame))

This seems unrelated to similar #11848.  Instead,

| Give , and .@ doc strings.  Fixes bug #24561.


seems to be causing this issue this time; probably

  (get function 'reader-construct)

should test whether FUNCTION is really bound to a symbol.


Thanks in advance,

Michael.

Sorry about this.  You're absolutely right, a `symbolp' is needed before
those `get's (in two places).

I've pushed a fix to master, and am closing this bug.

Thank you, too!
