           Summary: Crash in kontact todo-list when doing multiple
                    concurrent operations
           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: kdebjp at gmail.com


Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
What I was doing:
1) Started up kontact
2) Checked my email and read some feeds
3) Switched to the Summary view
4) Switched to the todo-list
5) I'm using akonadi as backend, and for some reason it sometimes a long time
before the todo-list is shown (this is problem that has surfaced recently). I
got impatient and attempted to select a category in the search bar.
6) Kontact crashed
