Bug 439973

Application: systemsettings5 (5.22.80)

Qt Version: 5.15.3
Frameworks Version: 5.85.0
Operating System: Linux 5.8.0-59-generic x86_64
Windowing System: X11
Distribution: KDE neon Unstable Edition
DrKonqi: 5.22.80 [CoredumpBackend]

-- Information about the crash:
- What I was doing when the application crashed:
I installed "Volantes Cursors" cursor theme via GHNS window of Cursors KCM and appllied it to my system.
I  switched to another KCM and switched back to Cursors KCM, then I removed "Volantes Cursors" cursor theme via GHNS window,
clicked on another KCM, clicked on "Discard" button of apply/discard prompt and System Settings crashed.

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() = 0x0}
