Bug 417415

Application: systemsettings5 (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.67.0
Operating System: Linux 5.3.0-28-generic x86_64
Distribution: KDE neon User Edition 5.17

-- Information about the crash:
- What I was doing when the application crashed:

I have opened the Web Shortcuts systemsettings page via search for "Web", then cleared the search field, then deleted "Ecosia-Suchmaschine" and added a custom "Ecosia" shortcut with the correct URL. After leaving the window open for a while (and using the new shortcut), I closed the systemsettings window again. In this moment, the crash reporter appeared.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Systemeinstellungen (systemsettings5), signal: Segmentation fault
