[Geary] duplicate emails and unread counts

[Federico Bruni <fede inventati org>]

Hi all

I have an email account (dovecot) where I often communicate with other 
people through an "alias email" (meaning that it forwards the emails to 
each of us). As everybody replies to all, when someone replies to me 
and the alias email, Geary is not able to count both (identical) emails 
as read.

In the left pane I see some unread messages, even if in the central 
pane there's no unread message.
The only way to reset the unread count is logging into the webmail, 
where the unread messages are visible and mark them as read.

In a nutshell, Geary marks the thread as read correctly in the thread 
view (central pane), but it fails to sync with the server. I think.

Did anybody experience the same?
Should I open a new issue on the tracker?
Do you need a log file to debug it? (in this case I should send it 
privately to a developer)

Thanks
Federico
