Deleting seen state file keeps unstable seen state for mailbox

[Ismaël Tanguy]

Hello

we're still stuck with inconstant state file.
This problem happen with differents clients (Thunderbid, Apple Mail, 
Iphone, webmail,..).

We have just make a tcpdump between a client and the server.
At the beginning of the capture, the client marks a mail with Seen Flag 
(line 1&2).
Then, he moves the mail to the Trash (line 7 & 8).

Thenseveral of his Seen mails is marked back as Unseen.
I'm not sure that this appears in this capture, doesn't it?
Also, I'm not an expert of the IMAP protocol, are the lines 10, 13, 19 OK?
The numeric tag (2472, 2477) doesn't answer to client's tag and all come 
from the server.

Is this the standard behavior?
