           Summary: akonadi crashes when modifying the times of an event
                    in korganizer
           Product: Akonadi
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: ICal file resource
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: mharvan29 at gmail.com


Application: akonadi_ical_resource (0.1)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-25-generic i686
Distribution: Ubuntu 10.04.1 LTS

-- Information about the crash:
More than half the times I resize an event in korganizer with the mouse,
akonadi segfaults. Resizing or moving an event with the mouse results in
modification of the start / end times of the event.

Akonadi crashed (segfault) more than half the times I tried resizing an event.
At least once Akonadi has not crashed.

The crash can be reproduced some of the time.

 -- Backtrace:
Application: Akonadi Resource (akonadi_ical_resource), signal: Segmentation
