Subject: Gnus and eieio bug breakage?
Date: Sat, 23 May 2015 17:15:31 +0200

Hi,

I'm using Gnus-git and Emacs-git since I wanted to test some Gnus
patches.

However, the head of Gnus-git seems to break something related to eieio in
my normal setup.  I don't really understand what is going on, but it seems
to relate to authinfo, and it breaks among others find-file.

Note that I remove gnus-git and rely on the version in Emacs-git I have no
errors.  From emacs -q I have no errors.  I'm not sure exactly what in my
setup makes it break.

Below are two backtraces, prefixed with "*".

Regarding the patches I'm working on, should I rebase them against
Emacs-git rather gnus-git in case one or the other is out of date?

Thanks,
Rasmus

Perhaps, the lisp/gnus-fallback-lib/eieio sub-directory of your gnu repo
clone is in load-path so that the files there shadow the regular eieio
stuff?

Indeed when I remove /usr/share/emacs/site-lisp/gnus/fallback-lib Emacs
works again.

Is that then a package error?  Or is it a Gnus bug?

Thanks,
Rasmus

Sorry for the late response; due to a misunderstanding the Gnus bug
reports went to a part of the bug tracker I wasn't checking.

Packaging error, perhaps.  But now that git Gnus doesn't exist any more,
this shouldn't be an issue any more.  :-)
