Thanks for submitting the bug report.

As mentioned in the Kasts matrix room, the crash is due to weird behaviour of the `Instantiator` inside the Kirigami `NavigationTabBar` component.

It took quite a while, but this has finally been merged, and today it was released as part of KF 5.109.0.  It could still take a while before it hits downstream repos, though.

Feel free to re-open if it turns out that the problem isn't solved by KF 5.109.0.

Last version of flathub works well in librem5 with `sudo flatpak override --env=QT_QUICK_CONTROLS_MOBILE=1 org.kde.kasts`. Thank you very much for your work.

Thanks for confirming (since this was a very tricky bug to reproduce).
