Application: filelight (22.12.0)

Qt Version: 5.15.7
Frameworks Version: 5.101.0
Operating System: Linux 5.15.85-1-lts x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.26.4 [KCrashBackend]

-- Information about the crash:
A crash may occur, when hovering over different items after triggering a rescan.

To reproduce:
1. Scan a directory with a lot of contents.
2. Hover over some item, causing a tooltip to appear.
3. Rightclick on any item and trigger a rescan. Wait for it to complete.
4. Hover over some other item(s). A crash should happen eventually. Not all items cause a crash, but I've found that it's consistent in which ones do.

I can reproduce this on a computer with an AMD cpu and gpu that runs wayland, and a laptop with an Intel cpu and igpu that runs xorg. Both run the same OS and KDE version. The attached trace information is from the amd/wayland computer, I will add the trace information from the intel/xorg laptop.

The crash can be reproduced every time.
