Subject: 25.0.95; rudel incompatible with eieio bundles in emacs 25
Date: Fri, 15 Jul 2016 18:05:10 +0200

dear emacs group,

i tried to get rudel (collaborative editing environment) running with
emacs version 25. the same minimal emacs configuration runs in emacs
24, but with 25 i get the error:
slot-value: eieio-oref called on a class: rudel-backend-factory
when loading rudel.el.

if i run the rudel initialization with (setq debug-on-error t) i get:

Debugger entered--Lisp error: (error "eieio-oref called on a class:
rudel-backend-factory")
  signal(error ("eieio-oref called on a class:
rudel-backend-factory"))
  error("eieio-oref called on a class: %s" rudel-backend-factory)

i prepared a minimal configuration for you to test with:
https://github.com/gizmomogwai/rudel
just set the EMACS env variable to your emacs binary (e.g. for me export EMACS=
~/bin/osx/emacs/25.0.95/bin/emacs) and run rudel-client.

i think the problem is related to:
https://lists.gnu.org/archive/html/bug-gnu-emacs/2015-05/msg00221.html
but my elisp skills are not up to the task!

perhaps you could give some hints on how to solve this.

thanks in advance,
christian köstlin
