Bug 474068

Application: plasma-discover (5.27.7)

Qt Version: 5.15.10
Frameworks Version: 5.110.0
Operating System: Linux 6.4.11-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.7 [KCrashBackend]

-- Information about the crash:
I uninstalled https://dl.flathub.org/repo/appstream/org.polymc.PolyMC.flatpakref and chose to delete its "settings and data". Pressing the latter caused the crash, it appeared.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
