Bug ID: 392658
Summary: Systemsettings crashes when searching while on the
screen corner behaviour screen
Product: systemsettings
Version: 5.12.4
Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

## Description
When customizing the screen corner actions under system settings, searching for
a different settings entry will reliably cause systemsettings to crash.
## Steps to reproduce
1. Navigate to the screen corner settings pane
2. Search for any other settings menu, e.g. "Fonts". Perform a few searches if
the first one doesn't result in a crash.
3. Systemsettings will crash
