Bug 440914

Application: systemsettings5 (5.18.5)

Qt Version: 5.12.7
Frameworks Version: 5.76.0
Operating System: Linux 5.3.18-59.16-default x86_64
Windowing system: X11
Distribution: "openSUSE Leap 15.3"

-- Information about the crash:
- What I was doing when the application crashed: At the time of attempting to install a splash theme from System Settings (I forget which, think it was Snowy Night Miku?) the application crashed, I have since installed the debug symbols to generate a usable report.

Sorry if my description of what happened wasn't very helpful, I don't frequently submit in depth bug reports

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
