           Summary: Bad behaviour of Kontact when automatically launched
                    at startup
           Product: kontact
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: mircea.sava at gmail.com

Application: kontact (4.4.7)
KDE Platform Version: 4.5.2 (KDE 4.5.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35.6-48.fc14.i686 i686
Distribution: "Fedora release 14 (Laughlin)"

-- Information about the crash:
- What I was doing when the application crashed:
Finishing starting up my system.
- Unusual behavior I noticed:
I got a prompt that said: "Kontact already seems to be running on another
display on this machine. Running Kontact more than once can cause the loss of
mail. You should not start Kontact unless you are sure that it is not already
running."
First time I exited the prompt without starting Kontact 'again', but after that
I had no kmail icon in system tray nor the kontact program in System Monitor.
Second time around (and third and forth) I clicked on Start Kontact button on
the specified prompt only to notice two instances of kontact running, with the
crash occuring soon after.
- Custom settings of the application:
Kmail is set to always show the icon in the system tray, therefore running
always in the background.

The crash can be reproduced every time.

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