Bug 462567

Application: kalgebra (22.08.3)

Qt Version: 5.15.7
Frameworks Version: 5.100.0
Operating System: Linux 6.0.10-arch2-1 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
Steps to produce the error:

1. Open KAlgebra
2. Click on "3D Graph" tab
3. Click anywhere on the application except for the title bar or another tab.
Result: KAlgebra immediately crashes
Expectation: KAlgebra shows 3D Plot tab and has normal functionality.

Additional information:

On step 2, when the tab is clicked, the tab will be highlighted, but the application will not display the 3D graph page, and stays displaying the page that I was on before clicking on the tab.

If I use KAlgebra Mobile, following the above steps results in a blank application screen with the exception of the sidebar, and the top toolbar with "Add plot", "save" and "reset viewpoint" buttons.

The crash can be reproduced every time.

-- Backtrace:
Application: KAlgebra (kalgebra), signal: Segmentation fault
