We recently refactored the todo model, could you see if you can still reproduce this issue? Thanks!

That is, if you can compile Kalendar from source, otherwise you might need to wait until the next release :) (In reply to Claudio Cambra from comment #2) > (In reply to Claudio Cambra from comment #1) > > We recently refactored the todo model, could you see if you can still > > reproduce this issue?

Couldn't compile, here's the error:

It seems 5.90 is less than 5.88. What am I doing wrong?

What am I doing wrong? You are missing the package qqc2-desktop-style The name of the package I was missing is libkf5qqc2desktopstyle-dev, and it wasn't listed as a requirement in the project page. Anyway, I built it and tried again. As you can see here https://nextcloud.samuelezappala.it/s/mT4ELtPxCDGwrP8 if I'm in "All tasks" view, expand a task and then select a calendar, it just crashes. If I go from a calendar to an other it hangs and eventually Plasma asks me to close it.

This crash should be fixed now, could you test the latest commits from the git master version of Kalendar? Thanks again I tride commit 349c3066 and 6ebf38e9, the result is the same but I don't really understand what's happening: https://nextcloud.samuelezappala.it/s/qgTiAwD2WQpYAJS I'm sorry I couldn't attach a crash report, but the last thing I do (select a calendar different from the one in which the task I expanded is) just hangs the program.

- What I was doing when the application crashed:
I succeded in making it crash again: changing task calendar was sufficient.

Thanks! Created attachment 146107 [details] New crash information added by DrKonqi kalendar (0.4.0) using Qt 5.15.3 Ok now all subtasks are expanded, without an option to make them collapsed by deafault, but this is clearly not important now. Going from "All tasks" to a specific calendar is not a problem anymore. I mean, the problem appeared expanding a task in its subtasks, but now it's all expanded; we can say that doiing the reverse (collapsing a task and selecting a specific calendar) doesn't create issues. The same with going from a calendar to another calendar: no issue anymore. But... - What I was doing when the application crashed: I managed to make it crash collapsing all the tasks in a specific calendar and changing calendar. i tried with the green calendar and it didn't happen; I don't know if it's related to calendar with more than a few tasks.

I've added a new and improved fix that should, fingers crossed, retain the prior behaviour of collapsed tasks by default while still preventing the crashing, including in the case you provided above. Could you try the latest commit? Thanks again!

Application: kalendar (0.4.0) Qt Version: 5.15.3 Frameworks Version: 5.90.0 Operating System: Linux 5.13.0-27-generic x86_64 Windowing System: X11 Distribution: KDE neon User - Plasma 25th Anniversary Edition DrKonqi: 5.23.5 [KCrashBackend] -- Information about the crash: - What I was doing when the application crashed: I tried it several times, sometimes Kalendar just hangs and after some time Plasma proposes to terminate it, sometimes it directly crashes. This happens only when I go to the tasks view, select "View all tasks", then expand the subtasks of a task and then select a random calendar to filter the view.
