           Summary: folder mis-sorted, messages not shown
           Product: kmail
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org

Version:            (using KDE 3.5.9)
Installed from:    Debian testing/unstable Packages

While reading mails in an IMAP folder (reading, deleting, reading next, etc, periodic reloads), the sorting of messages suddenly gets screwed up. The unread messages get to the top of the list (while they should be in the bottom of the list, my folders are sorted according to "Order of Arrival"). After this event, the unread messages can't be read, if I select them, their message body remains blank.

Switching to other folder and switching back doesn't help, neither restarting kmail. When switching from the screwed up folder to another and back, kmail crashes with some probability, but not always.

The only workaround I've found is deleting 
~/.kde/share/apps/kmail/imap/.$WHEIRD_NUMBER.directory/.$FOLDERNAME.index.*
files.

I can't reproduce the bug intentionally, but it happens like once or twice a week, so it's getting annoying. The problem appeared about a month ago I think.
