ERROR: AnnounceSystem failed

[anonymous]

I just tried to upgrade from the 0.11 announcer plugin to 0.12dev plugin and haven't been able to send any notifications. I have pasted the error below.

Additional information: I can assure you that my trac.ini has a good email server configured because the configuration I am using works with the default notificaiton system and the 0.11 Announcer plugin.

Any help you can provide is much appreciated. Thanks!
