The segfault must have been due to something I inadvertently introduced into my configuration while trying to set up irssi-plugin-xmpp.
After cleaning up my configuration and running /xmppconnect, I was able to establish a successful connection and all is working. I know I should have saved the old configuration file, since a segfault isn't desirable even with invalid configuration settings. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
