Application: dolphin (21.12.2)

Qt Version: 5.15.2
Frameworks Version: 5.91.0
Operating System: Linux 5.18.7-100.fc35.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 35 (KDE Plasma)
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:

Moving files at the CLI while Dolphin had that tree view open.
Nine of ten times there's no issue, but sometimes it falls over. Here's one log that managed to populate messages. Usually it just reports 'KCrash: Application 'dolphin' crashing...' with nothing really helpful.
`dolphin[171949]: org.kde.dolphin: Invalid item range (index: 17 , count: 0 )`

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
