           Summary: Akonadi console crashes when changing selection in
                    treeview (browser)
           Product: Akonadi
           Version: unspecified
          Platform: Fedora RPMs
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: akonadiconsole
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: kde-bugzilla at dadommas.de


Application: akonadiconsole (0.99)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.8.0
Operating System: Linux 2.6.40-4.fc15.x86_64 x86_64
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:
Due to an earlier attempt at migrating to kmail2 I had old stuff in "KMail
folders" and wanted to get rid of it.
I selected all children items of "KMail folder" in the treeview and after not
being able to delete them all at once I wanted to select a single item. =>
crash

I'm about to try again in a few seconds so I will be able to tell if this is
reproducible
