           Summary: Crash in korganizer when quitting with kquitapp
           Product: korganizer
           Version: unspecified
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: korganizer-devel at kde.org
        ReportedBy: david.narvaez at computer.org


Application: korganizer (4.8 pre-git-719de66 (2011-11-06))
KDE Platform Version: 4.7.3 (4.7.3) (Compiled from sources)
Qt Version: 4.7.4
Operating System: Linux 3.0.3-gentoo-libre x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
- What I was doing when the application crashed:

Open KOrganizer, then from a terminal do kquitapp korganizer. This is also
reproducible if you log out of your session while KOrganizer is open.

While debugging, I realized this has to do with the sModel variable declared at
ktodoview.cpp:66, which is destroyed before it's last access. I tried reading
through the documetation of K_GLOBAL_STATIC to see if there's any evident fix
that can be applied, but couldn't make any progress.

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer (korganizer), signal: Segmentation fault
