           Summary: korganizer crashes when filtering involves sub-to-dos
           Product: korganizer
           Version: 4.2.2
          Platform: unspecified
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: korganizer-devel at kde.org
        ReportedBy: vmpereir at fc.up.pt


Version:           4.2.2 (using 4.2.2 (KDE 4.2.2), 4.2.2-7.fc10 Fedora)
Compiler:          gcc
OS:                Linux (i686) release 2.6.27.21-170.2.56.fc10.i686

When I try to select a view filter that tries to filter sub-to-dos korganizer
crashes always.

1. Create a to-do;
2. Create a sub-to-do of the one above;
3. Assign a category to that sub-to-do, say "Meeting";
4. Create a view filter that shows only the category "Meeting";
5. Go to a view without any filter and select this filter through
"View->Filter";
6. korganizer crashes with the backtrace given below.

What is even stranger is that the crash only occurs if I select the filter
starting from a "No filter" situation. For example if I select another view
filter (not involving sub-to-dos) and, immediately after, select the filter
constructed as described above, korganizer doesn't crash. It only happens if I
select the filter from a "No filter" view.
