543029 - Sometimes mark mail messages unread

Status: RESOLVED DUPLICATE of bug 540554

(Thunderbird :: General, defect)

Description

[Martin Strejc]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; cs; rv:1.9.2) Gecko/20100115 Firefox/3.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; cs; rv:1.9.1.7) Gecko/20100111 Thunderbird/3.0.1

Thunderbird marks a single message, few messages or all messages in any folder (it happened in Inbox, Outbox and also other my custom folder) as "unread" event it has been previously marked "read". When you use to mark read back again manually and go to another folder and back or close Thunderbird and run it again, those meesages are in state "unread" back again. Folder maintenance doesn't work to fix that problem. It comes sometime in any folder. Tested just with IMAP connection. Probably it should be a server side error. There is Postfix/Dovecot running on the mail server. 

Reproducible: Sometimes

Steps to Reproduce:
1.unknown/it happens (already read messages are marked unread)
2.mark message(s) read
3.make folder mainenance
4a.swith displayed folder to another and back or
4b.close the ThunderBird window and run/open program again
5.see the folder
Actual Results:  
Read/read marked messages are marked unread

Expected Results:  
Read/read marked messages are marked read

The similar problem was happened in Thunderbird 2.0 even that was not so often. Actually it is more over once a day, it was also in 2.0 few than once a month, specially for common marks (important/work/private/to do...) not for read/unread status.
