           Summary: Kontact crash after quitting it
           Product: kontact
           Version: unspecified
          Platform: openSUSE RPMs
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: jangerrit at weiler-marker.com


Application: kontact (4.4 rc2)
KDE Platform Version: 4.3.98 (KDE 4.3.98 (KDE 4.4 RC3)) "release 218"
Qt Version: 4.6.1
Operating System: Linux 2.6.31.8-0.1-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
Kontact is started through the Autostart Systemsettings module (by the way:
everything appears there twice, maybe that's important). If I login I get the
message that Kontact is already started. There's no tray icon (neither KMail's
nor Akregator's one) so it start Kontact, tough. Then suddenly there are two
tray icons for KMail and two for Akregator. I close Kontact through Ctrl+Q and
the four tray icons disappear. Then the crash dialog with the backtrace
appears. This happend at two logins, if I start Kontact through KRunner later
everything is normal.

The crash can be reproduced some of the time.

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