Frameworks Version: 5.115.0
Operating System: Linux 6.8.0-57-generic x86_64
Windowing System: X11
Distribution: Ubuntu 24.04.2 LTS
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
The application consistently crashes with a segmentation fault when attempting to edit the "Overview" page.

-- Steps to Reproduce:
Open the KDE System Monitor application.
Navigate to the "Overview" tab (this is usually the default tab).
Locate the "Edit Page" button, typically found in the toolbar or a context menu related to the displayed information.
Click on the "Edit Page" button.
Expected Behavior:

Clicking the "Edit Page" button should open a dialog or interface allowing the user to customize the widgets and information displayed on the "Overview" page.

-- Actual Behavior:
The System Monitor application crashes with a segmentation fault immediately or shortly after clicking the "Edit Page" button. The application window closes.

The crash can be reproduced sometimes.

-- Backtrace:
