           Summary: Kontact crashes after restart under conditions
           Product: kontact
           Version: 4.6 pre
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: stephan at peccini.fr


Application: kontact (4.6 pre)
KDE Platform Version: 4.5.85 (4.6 Beta2)
Qt Version: 4.7.1
Operating System: Linux 2.6.35.9-64.fc14.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Sometimes for a reason I can't explain, kmail is not able to propose the good
information about unread mails (it indicates 2 unread mails even none where
there are numerous); kmail is also unable to go and select the next mail when I
am deleting one.
At this moment, I close kontact, trying to get kmail working again. Kontact is
configured to open knode as the default application. When I try to select kmail
after starting kontact, nothing happen and kontact crashes in a few second.
In normal conditions (without problems of unread mail notification in kmail),
restarting kontact does not finish in a crash.

The crash can be reproduced every time.

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