           Summary: Kmail crashes after closing (two Kmail instances load
                    after login)
           Product: kontact
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: pavel.mala at gmail.com


Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-20-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
During login, kontact is started twice and a dialog is presented saying that
Kontact is already running and running a second instance could be dangerous.
Clicking "No" closes both. Clicking "Yes" opens both, named "Kontact" and
something like "Kontact ", each with an icon in the tray. Closing "Kontact"
crashes kontact and closes both windows. Closing "Kontact " first did not crash
them until I closed "Kontact" (I only did this once).

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