           Version: 4.4.3
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED

          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: rrs at researchut.com


Application: kontact (4.4.3)
KDE Platform Version: 4.4.4 (KDE 4.4.4)
Qt Version: 4.6.3
Operating System: Linux 2.6.32-5+iwlagn.1-amd64 x86_64

-- Information about the crash:
Kontact lately has been showing occasional crashes while remaining idle. I am
not very sure for the cause though. The only delta is that I have hand
installed kcaldav.

The crash can be reproduced some of the time.

 -- Backtrace:
