           Summary: Kontact crashes while startup in
                    KDescendantsProxyModel
           Product: kontact
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: bjoern.ricks at intevation.de


Application: kontact (4.6 pre)
KDE Platform Version: 4.4.93 (KDE 4.4.93 (KDE 4.5 >= 20100713)) (Compiled from
sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.26-2-xen-686 i686
Distribution: Debian GNU/Linux unstable (sid)

-- Information about the crash:
During the startup of Akonadi I tried to open the message composer. After
clicking on the create message button kontact directly crashed. Now it's not
going to start anymore and crashes on every startup.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
