           Summary: akonadi nepomuk feeders crashed when attempting to
                    display error message
           Product: Akonadi
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: Nepomuk Feeder Agents
        AssignedTo: tokoe at kde.org
        ReportedBy: kde at randomguy3.me.uk
                CC: vkrause at kde.org, kdepim-bugs at kde.org


Application: akonadi_nepomuk_contact_feeder (0.1)
KDE Platform Version: 4.5.67 (4.6 >= 20100901) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.35-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:

I pulled Nepomuk out from under Akonadi (I'd killed the virtuoso-t processes
before starting akonadi, and stopped nepomuk altogether while Akonadi was
running).  The contacts feeder and the email feeder both crashed immediately.

-- Backtrace:
Application: Akonadi Agent (akonadi_nepomuk_contact_feeder), signal:
