           Summary: Kontact crashes at random. Multiple times a day.
           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: fock at nano.ku.dk


Version:           Kontact: 1.4.2 (using KDE 4.2.2)
OS:                Linux
Installed from:    Ubuntu Packages

Kontact crashes at random.  It happens to me multiple times a day, but I can
find a systematic event which courses the crash. 

When restarting kontact the last state of kmail is restored, except for the
marking of some of the read mails as unread.
