bug#4443: ERC gets freezed, Emacs 23

[Mario Castelán Castro]

When i click somebody ip (In the form n=us...@a.b.c.d), emacs gets
freezed and i must press C-g to restore it.
I think this is a bug, i are using emacs 23.

I can't seem to reproduce this. Could you provide step by step
instructions, starting from `emacs -Q'?

[Mario Castelán Castro]

Sure, i start emacs with -Q
then i use M-x erc and all the default options but nick marioxcc and
my password (i can't say it of course)
then ERC connects to freenode server, i type "\whois chanserv" in the
"freenode" buffer
i get the following message:
*** ChanServ is Channel Services (ChanServ@services.)
*** ChanServ is/was on server irc.freenode.net (http://freenode.net/)
*** ChanServ is an identified user
With the mouse i click in "ChanServ@services.", emacs gets freezed and
i type C-g to restore it
Another example:
I type "\whois marioxcc" (or any other user) and then i click it IP, as example
\whois marioxcc
*** marioxcc is Mario Castelan Castro (n=us...@200.92.164.103)
*** marioxcc is on channel(s): #venenux #lisp-es #lisp #gnu #emacs-es
*** marioxcc is/was on server irc.freenode.net (http://freenode.net/)
*** marioxcc is an identified user
*** marioxcc is an identified user
then i click "n=us...@200.92.164.103" and emacs gets freezed, i must
type C-g to restore it.
The same happens when someone enter the channels and i click it user. as example
*** Azag (n=us...@pc-26-211-120-200.cm.vtr.net) has joined channel #venenux
And then i click in "n=us...@pc-26-211-120-200.cm.vtr.net"
Thanks in advance

Please do the following:

- In Options menu, enable "Enter Debugger on Quit/C-g"
- Trigger the problem
- Send the backtrace

Also, please switch to a server buffer, do C-h m, and send us the list
of enabled minor modes from the first and subsequent lines.

The problem is due to erc-button.el having a rule in erc-button-alist
that calls "finger". I see no reason to keep that rule around, so
I'll delete it the next time I sync up ERC with Emacs.

Is there any reason why we can't just delete the

("(\\(\\([^~\n \t@][^\n \t@]*\\)@\\([a-zA-Z0-9.:-]+\\)\\)" 1 t finger 2 3)

in the Emacs sources directly?
