Bug 447904

Application: systemsettings5 (5.23.4)
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.89.0
Operating System: Linux 5.15.11-gentoo x86_64
Windowing System: X11
Distribution: "Gentoo Base System release 2.7"
DrKonqi: 5.23.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I had the About Krohnkite dialog open (system settings -> kwin scripts -> about Button of Krohnkite). Then i selected the header text "Krohnkite" and right clicked it. This cause system settings to crash.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = {<No data fields>}}
