Description Christian González 2023-12-10 18:19:43 UTC

Application: dolphin (23.08.3)

Qt Version: 5.15.11
Frameworks Version: 5.112.0
Operating System: Linux 6.5.13-1-MANJARO x86_64
Windowing System: Wayland
Distribution: Manjaro Linux
DrKonqi: 5.27.9 [KCrashBackend]

-- Information about the crash:
Weird behaviour. reproducible here on Manjaro current.
in a folder, create folder "A" and place a file in it. Create folder "B" and place a file in it.
now expand folder B using the "greater than" sign on its left. close it again.
Now expand folder A using the same technique.

Result: The folder A content is displayed below folder B (!)
When you now mark folder A and press "Del" on the keyboard, Dolphin crashes.

The reporter is unsure if this crash is reproducible.

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

I experienced the same weird glitch with the contents (visually) expanding below the wrong folder and the subsequent crash when trying to delete those contents.
