[ESS-bugs] ess puts nil in load-history

[Thomas Alexander Gerds]

Dear ESS team

on emacs 26.0.50.1 after loading ess (16.10-1 [elpa: 20170206.310]) via

(use-package ess-site :ensure ess)

I get

(mapcar 'car load-history)

"/home/tag/emacs-genome/genes/ess-20170206.310/lisp/ess-site.elc" nil
"/home/tag/emacs-genome/genes/ess-20170206.310/lisp/ess-toolbar.elc" "/home/tag/emacs-genome/genes/ess-20170206.310/lisp/ess-mouse.elc"

the 'nil' occasionally causes an error when help--loaded-p does this:

(dolist (x load-history) (if (string-match-p re (car x)) (setq done t)))

can anyone recognize, reproduce or even better solve this problem?

thanks Thomas
