SUMMARY
STEPS TO REPRODUCE
1. navigate to settings -> Configure Kontact...
2. close the configuration window using the close button
3. repeat steps 1 and 2 (alternatively, close the Kontact main window using the
close button)

the application crashes due to a segmentation fault
EXPECTED RESULT
SOFTWARE/OS VERSIONS
Windows:
macOS:
(available in the Info Center app, or by running `kinfo` in a terminal window)
Linux/KDE Plasma: Gentoo Linux
KDE Plasma Version: 6.5.4
KDE Frameworks Version: 6.21.0
Qt Version: 6.10.1
ADDITIONAL INFORMATION
When closing the configuration window, the function
KontactKCMultiDialog::closeEvent deletes all KCModules currently held, after
which the window gets hidden. When reopening it, the previously deleted
KCModules are not recreated. The next activation of
KontactKCMultiDialog::closeEvent triggers a NULL pointer dereference by
attempting to remove the already deleted KCModules once again.
