Possible bug: Unable to register with Google Talk

Hello,
I am trying to connect with google talk using Asterisk 1.4.13 on a Debian Etch system.
I know that the given username and password are correct since I’ve verified them with a windows client.
I get the following error message:
Connected to Asterisk 1.4.13 currently running on pulce (pid = 2118)
Verbosity is at least 3
– Remote UNIX connection

Here is the jabber.conf file I am using:
[general]
debug=no ;;Turn on debugging by default.
autoprune=no ;;Auto remove users from buddy list.
autoregister=yes ;;Auto register users from buddy list.

[asterisk] ;;label
type=client ;;Client or Component connection
serverhost=talk.google.com ;;Route to server for example,
;; talk.google.com
username=myusername@gmail.com/Talk ;; Google mail user name
secret=mypassword ;; Password
port=5222 ;;Port to use defaults to 5222
usetls=yes ;;Use tls or not
usesasl=yes ;;Use sasl or not

Any ideas?
