(Sorry for out-of-order messages, just authenticated.)

I tried the above, and loading helm now gives:

Debugger entered--Lisp error: (wrong-type-argument eieio--class-p 
helm-locate-source)
  signal(wrong-type-argument (eieio--class-p helm-locate-source))
  eieio--class-slot-initarg(helm-locate-source name)
  (setq slot (eieio--class-slot-initarg class s))
  (while (consp --cl-var--) (setq s (car --cl-var--)) (setq slot 
(eieio--class-slot-initarg class s)) (setq slot-val (slot-value object slot)) 
(if slot-val (progn (setq --cl-var-- (cons (cons s (if (eq t slot-val) nil 
slot-val)) --cl-var--)))) (setq --cl-var-- (cdr --cl-var--)))
  (let* ((--cl-var-- (object-slots object)) (s nil) (slot nil) (slot-val nil) 
(--cl-var-- nil)) (while (consp --cl-var--) (setq s (car --cl-var--)) (setq 
slot (eieio--class-slot-initarg class s)) (setq slot-val (slot-value object 
slot)) (if slot-val (progn (setq --cl-var-- (cons (cons s (if ... nil 
slot-val)) --cl-var--)))) (setq --cl-var-- (cdr --cl-var--))) (nreverse 
--cl-var--))
