           Summary: Akonadi Console crashes during shutdown if a job is
                    active
           Product: Akonadi
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: akonadiconsole
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: mpyne at kde.org


Application: akonadiconsole (0.99)
KDE Platform Version: 4.7.2 (4.7.2) (Compiled from sources)
Qt Version: 4.8.0
Operating System: Linux 3.1.0-rc9-00020-g3ee72ca x86_64

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

I was in Akonadi Console trying to troubleshoot a very annoying bug causing
ItemFetchJobs to take a very long time (about a minute each) to complete.
Apparently when I closed the application with a job still outstanding it
prompted a KJob to emit its partial result (on that note, maybe look at KIO...)
which tried to load a pixmap, which crashed the console.

kdepim is 5a649889f8d4c8b9106632e48cb2ee9772bd82a2. Akonadi, kdepimlibs,
kdepim-runtime, kdelibs are all git master checkouts from approximately the
same time (except that kdelibs is branch KDE/4.7).

I have not tried to reproduce as I consider that the bug is probably
inconsequential, but it does seem that parts of the shutdown logic should be
modified to avoid this trap.
