Matching signals in Python

[Sam Morris]

I'm trying to write a simple python program to listen for Evolution's new
mail signal. The code I have is as follows:

---
import gobject
import dbus

def print_mail (mailbox):
	print 'mail: ', mailbox

bus = dbus.SessionBus ()
bus.add_signal_receiver (print_mail,
                         signal_name='Newmail',
                         dbus_interface='org.gnome.evolution.mail.dbus.Signal')

loop = gobject.MainLoop ()
loop.run ()
---

But print_mail is never called. The messages going over the bus look like
this:

signal sender=:1.24 -> dest=(null destination)
interface=org.gnome.evolution.mail.dbus.Signal; member=Newmail
 string "spool:///var/mail/sam#INBOX"

This is with Dbus 0.61. Could someone please point me in the right
direction?
