Description David E. Narvaez 2011-11-07 07:50:38 UTC
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.

Do you have any filters set? Like filtering by category or name.

Do you have sub-todos, and does it crash without sub-todos ?

Does it crash with an empty view ?

Do you have the sidebar mini-todo-view visible? Does it crash without it being visible ?

> Do you have any filters set? Like filtering by category or name.

No.

> Do you have sub-todos, and does it crash without sub-todos ?

No.

> Does it crash with an empty view ?

Yes. I didn't even know about TODOs in KOrganizer until I started debugging this issues. It actually crashes even if I kquitapp while at the Calendar view without ever visiting the TODO view.

> Do you have the sidebar mini-todo-view visible? Does it crash without it being
> visible ?

Yes, I have that sidebar. I haven't tried replicating it without the sidebar. I'll try that in a couple of hours.
