           Summary: Kontact crashed for no apparent reason
           Product: kontact
           Version: 4.4.3
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: tanghus at gmail.com


Application: kontact (4.4.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-020634-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
I noticed the fan was spinning up so I guess it was checking mail or
subscriptions.
To me it looks like a Qt bug but I have no idea how to decipher backtraces :-/
