bug#17783: 24.4.50; ERC: custom-set-variables with erc-modules after a (require 'erc) causes network names to be nil unless 'networks' modules is used

bug#17783: 24.4.50; ERC: custom-set-variables with erc-modules after a (require 'erc) causes network names to be nil unless 'networks' modules is used

[Bradley M. Kuhn]

Put the following in FILE:

(require 'erc)
(custom-set-variables
 '(erc-modules (quote (button))))
(erc-select :server "irc.gnome.org" :port "6667" :nick "testignoreme1857" :full-name "Tester")

and call with emacs -Q -l FILE

As you connect to the IRC server, you'll see that the modeline -- initally
correct -- change the IRC network name "nil" after connecting.  If you
join a channel, that will be named #channel@nil, etc.

This problem does not occur if you switch the order of "(require 'erc)"
and the "(custom-set-variables)"

This problem also does not occur if you have "networks" in the
erc-modules list (since it changes the network name after connecting).

I discovered this problem because I still had a "(require 'erc)"
floating around in my .emacs, appearing before my "custom-set-variables" (from
years before when ERC wasn't part of Emacs).  This "(require 'erc)" isn't
actually needed, but it took a long time to determine what part of my
.emacs was causing the problem.

Do you know what it is that erc does when loading that makes this work
normally?

I've tried this in Emacs 27, and I was unable to reproduce is, so I'm
going to go ahead and guess that this has been fixed in the five years
since it was reported, and I'm closing this bug report.

If you're still seeing this, please reopen.
