           Summary: kontact crashes when in the task/todo list while
                    changing filters
           Product: kontact
           Version: unspecified
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: Divan.Santana at gmail.com

Application: kontact (4.4 rc2)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-17-generic x86_64
Distribution: Ubuntu 9.10

-- Information about the crash:
What I was doing when the application "Kontact" crashed:
I was in the task list "page" of kontact(control+5) and my "work" filter was
selected so I selected no filter as some tasks(and subtasks) were missing.
While switching between filters my kontact application crashed. There is two
problems/bugs. 1, kontact crashed, 2, Some of my tasks occasionally disappear.
I've noticed this since using tasks and sub-tasks. That's why this crash
occured, I was trying to see all my tasks.

Unusual desktop behavior I noticed:
Some of my tasks occasionally disappear. I've noticed this since using tasks
and sub-tasks. That's why this crash occured, I was trying to see all my tasks.

Custom settings of the application that may be related:
I use kolab to store my calendar/tasks/contacts. I'm not currently connected to
kolab when this happened. Not sure if this would still happen when I am
connected but I assume it would.

The crash can be reproduced every time.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
The current source language is "auto; currently c".
