           Summary: Messages without In-Reply-To: header are not properly
                    sorted in thread view
           Product: kmail2
           Version: 1.99.0
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: message list
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: kde at opensource.sf-tec.de


Version:           1.99.0 (using KDE 4.7.1) 
OS:                Linux

I'm refering to the thread "Who relies on
Soprano::Model::statement[s]Added|Removed signals?" on kde-core-devel. But this
happens also to other threads on this list (and likely anywhere else, too).
This can easily be spotted for all those mails injected by gmane.org.

What happens is that these mails have correct references, but no In-Reply-To:
header. These mails are then always shown as direct children of the mail
starting the thread, not those mails they are replies to.

Reproducible: Always

Steps to Reproduce:
Search this threads for mails injected by gmane.org users (they have the header
X-Injected-Via-Gmane: http://gmane.org/). For the thread mentioned above this
is e.g. this mail:

Message-ID: <slrnj8btu4.p7v.nospam at sshway.ssh.pusling.com>
References: <4E85A9B6.4070607 at kde.org> <1818577.X8mjX0lsAh at bluebox>
From: Sune Vuorela <nospam at vuorela.dk>
Date: Fri, 30 Sep 2011 17:09:24 +0000 (UTC)


Actual Results:  
The mail is shown as child of <4E85A9B6.4070607 at kde.org> (thread leader).

Expected Results:  
The mail is shown as child of <1818577.X8mjX0lsAh at bluebox>.

OS: Linux (x86_64) release 3.0.4-43-desktop
Compiler: gcc
