           Summary: Same message appears twice in Exchange-hosted IMAP-inbox
           Product: kmail
           Version: 1.9.7
          Platform: unspecified
        OS/Version: FreeBSD
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs kde org
        ReportedBy: mi+kde aldan algebra com


Version:           1.9.7 (using KDE 3.5.6, compiled sources)
Compiler:          gcc version 3.4.6 [FreeBSD] 20060305
OS:                FreeBSD (amd64) release 6.3-PRERELEASE

Every once in a while the same message would be listed twice in the inbox. Clicking on any of the entries would display the message, but deleting any of them will delete both.

Simply clicking back-and-forth between the messages will, eventually, get rid of the duplicate.

So far I only noticed this with the particular inbox hosted by an Exchange server (accessed via IMAP).

First observed in:

% kmail -v
Qt: 3.3.3
KDE: 3.3.1-6.RHEL4 Red Hat
KMail: 1.7.1

Still seen in the most recent release (accessing the same Exchange server).

A screen-shot (with some details erased) can be seen at http://aldan.algebra.com/~mi/duplicate-messages.png
One of the duplicates is selected (orange background), the other one is right above it.
