Date: Mon, 23 Mar 2015 22:06:41 -0400

Hi,

The patch removing iswitchb from ERC has left the command
erc-switch-to-buffer (C-c C-b in ERC) broken. From emacs -Q:

0. M-x toggle-debug-on-error RET
1. M-x erc RET and get connected
2. C-c C-b TAB

Debugger entered--Lisp error: (wrong-type-argument stringp (" *Minibuf-1*" . #<buffer  *Minibuf-1*>))

I never used ERC (and barely ever used IRC), so if you could expand on
"and get connected", that would be helpful.

It's sufficient to use the defaults in the interactive prompts for M-x
erc, so:

IRC Server: irc.freenode.net
IRC port: 6667
Nickname: somerandomnick
Password:

is fine.  This should result in a plain (as opposed to TLS) connection
to freenode IRC (Home page <https://freenode.net/>) without logging in or
joining any channels.

Great, thanks.  Should be fixed now,
