bug#12669: 24.2.50; invalid function when starting erc

[Ivan Kanis <ivan.kanis@googlemail.com>]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

1) emacs -Q
2) M-x erc
3) Press enter repeatedly

Seems to be commit 110553 that breaks it.
