XMLRPC ticket update doesn't trigger notifications

[sam@…]

We use the following options:

[notification]
always_notify_owner = true
always_notify_reporter = true

However when changes are made via XMLRPC emails are not sent out. Perhaps there is something else I should be doing? Could ticket.upate() be made to trigger emails. Seems like it should do the same things as a normal web-form ticket update.
