To reproduce:
- Select any email
- click "Reply"
- close the composer window without sending
- click "New secure email"
- enter something and click "Send"
-> email gets sent (without feedback), but window stays open
Cause: Current code assigns a new MessageDispatcher object, but fails to connect to its signals
