           Summary: KMail causes duplicate unread mail to appear in
                    webmail client
           Product: kmail
           Version: 1.13.5
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: IMAP
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: Leon.N.Maurer.08 at alum.dartmouth.org


Created an attachment (id=58725)
 --> (http://bugs.kde.org/attachment.cgi?id=58725)
screen shot of webmail that demonstrates problem

Version:           1.13.5 (using KDE 4.6.2) 
OS:                Linux

First, let me say that this looks like a KMail problem; other clients like
Apple's Mail (and Thunderbird IIRC) do not cause this problem.

If I have my university's webmail client open at the same time as KMail (as an
IMAP account), the problem shown in the attachment occurs. New emails appear
twice in the webmail client (in purple ellipse in attachment). The second
(grayed out) copy cannot be marked as read (see green ellipse in attachment
showing one unread message) and will not go away until after I sign out of the
webmail client (often I have to wait some time after that -- if I sign back in
too soon they will still be there).

I realize this might be a hard bug to fix because you probably don't have
access to this webmail client, but -- because other mail clients don't cause
this problem -- it does seem to be a problem with KMail and not with the
webmail, so I think you should be aware of it.

Reproducible: Always
