           Summary: kmail confused about message headers, mixing up messages
                    in the message list
           Product: kmail
           Version: unspecified
          Platform: Gentoo Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR

Version:           KMail 1.9.7 (using KDE 3.5.8)
Installed from:    Gentoo Packages
Compiler:          gcc (GCC) 4.2.2 (Gentoo 4.2.2 p1.0)
 
OS:                Linux

I'm using IMAP folders with my version of KMail. I've seen this bug for a while and decided to finally report it.

It seems to happen in larger mailboxes. For example, the inbox for my main e-mail account has 2610 messages. I've coped with the problem in the past, somewhat, by writing Perl scripts that are fired off by cron to move messages into an archive folder periodically.

In essence, KMail seems to get confused about message headers and mixes up messages. One example of this behavior is when I use the Search: box to search for a certain subject line. Messages matching that subject line are shown correctly, but when I select one, KMail displays an entirely different message and then changes the list entry to match that message, despite it not matching my search criteria.

I also find that clicking various messages that aren't downloaded yet will often cause their header to change and a different message to appear. Clicking back around the list causes headers to switch as different messages are displayed. It appears that when KMail displays another message, its list entry is not updated until a window event (such as moving the focus to another window) occurs.

I'll attach a series of screenshots showing the behavior. 

This bug seems related to #62452 but I'm not sure it's the same thing. #62452 is marked RESOLVED but there was another entry added at the end of 2004 and it doesn't seem to have been addressed since then.
