I certainly don't have more experience, but maybe it will help if I
report my own.

I have the very same problem with the following configuration:

Org mode version 9.0.8 (9.0.8-elpa @
/home/cochard/.emacs.d/elpa/org-20170606/)

GNU Emacs 24.5.1 (x86_64-redhat-linux-gnu, GTK+ Version 3.14.12) of
2015-05-07 on buildvm-08.phx2.fedoraproject.org

'uname -a' gives: Linux frac.u-strasbg.fr 4.1.13-100.fc21.x86_64 #1
SMP Tue Nov 10 13:13:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

I've had this problem since I updated org ELPA on 24 dec 2016 (NB: I
have not changed my GNU emacs version or GNU/Linux distribution).


I performed the following tests (all independently from one another),
all with a void .emacs file.

(1) With 'emacs --no-site-file'

-> the error is present.

(2) With 'emacs --no-site-file' 

and after commenting the line

(autoload 'nnir-article-group "nnir" nil nil 'macro)

in file /usr/share/emacs/24.5/lisp/gnus/gnus-sum.el (after having
gunzip'ed it) and also after having hidden the corresponding .elc file

-> the error is not present.

(3) With 'emacs --no-site-file --no-site-lisp'

-> the error is not present.

(4) With 'emacs --no-site-file'

and after hiding files nnir.el and nnir.elc, which are in dir
/usr/share/emacs/site-lisp/gnus-bonus

-> the error is not present.

The begining of file /usr/share/emacs/site-lisp/gnus-bonus/ is

This file contains: (require 'gnus-sum)
