           Summary: Kontact crashes during reassignment of sub-task as
                    independent task
           Product: kontact
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: henrik at klagges.com


Application that crashed: kontact
Version of the application: 4.3.0 rc2
KDE Version: 4.2.96 (KDE 4.2.96 (KDE 4.3 RC2))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-14-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
- Select a subtask of a task in the task list of Kontact
- open the menu on the subtask, e.g. with right-click
- select the menu entry that would dissociate the subtask from
  its parent task and re-enter it as a new task
- immediate crash after selection of the menu entry.

Note: I have a filter active that filters out the display of "done" tasks.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
