announcerplugin - ticket subscription not working

[henke.mike@…]

The plugin features like html emails and Component Subscriptions are working for me but Ticket Subscriptions like "Notify me of changes to tickets that I reported." is always on. If I disable LegacyTicketSubscriber then no emails are sent to the reporter.

trac.ini file:

[announcer]
ctxtnav_names = Watch This,Unwatch This
email_address_resolvers = SpecifiedEmailResolver, SessionEmailResolver
email_enabled = true
email_sender = SmtpEmailSender
email_to = undisclosed-recipients: ;
mime_encoding = base64
sendmail_path = sendmail
smtp_enabled = true
smtp_from = trac@xxx.com
smtp_port = 25
smtp_replyto = trac@xxx.com
smtp_server = xxx
smtp_subject_prefix = __default__
ticket_subject_template = $prefix #$ticket.id: $summary
use_public_cc = false
use_short_addr = false
use_sll = false
use_threaded_delivery = false
use_tls = false

[components]
announcerplugin.* = enabled
announcerplugin.subscribers.ticket_compat.legacyticketsubscriber = enabled
announcerplugin.subscribers.ticket_compat.staticticketsubscriber = disabled
announcerplugin.subscribers.ticket_groups.* = disabled
