DrKonqi auto-attaching complete backtrace.
Comment 2 Nicolas Fella 2025-12-21 13:54:53 UTC
This seems to happen specifically after disabling and re-enabling the notification applet in the system tray settings
Comment 3 Nicolas Fella 2025-12-21 13:58:47 UTC
Relevant QML expression is the onCountChanged in https://invent.kde.org/plasma/plasma-workspace/-/blob/master/applets/notifications/main.qml#L193
Comment 4 Nate Graham 2025-12-22 21:50:35 UTC
Looks almost the same as Bug 513527, but not *exactly* the same.

For my own education, how did you determine this from the backtrace?

Can also reproduce this with Qt 6.10.1 (from Arch packaging).
