Bug 439558

Application: systemsettings5 (5.21.5)
 (Compiled from sources)
Qt Version: 5.15.2
Frameworks Version: 5.82.0
Operating System: Linux 5.12.0-pf6-5402-r50lxx x86_64
Windowing System: X11
Drkonqi Version: 5.21.5
Distribution: "Gentoo Base System release 2.7"

-- Information about the crash:
- What I was doing when the application crashed:
I was disabling the startup service for the search folder because everytime my system starts up, it almost kills my machine with constants writes, sometimes writing more than 400 GB in less than 40 minutes. Doing this action caused the settings app to crash.

The reporter is unsure if this crash is reproducible.

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