Application: dolphin (23.08.5)

Qt Version: 5.15.13
Frameworks Version: 5.115.0
Operating System: Linux 6.8.0-31-generic x86_64
Windowing System: X11
Distribution: Ubuntu 24.04 LTS
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
When expanding a folder F1 in detail view, the folder contents will be displayed below a different folder F2 on the same directory-structure-hierachy-level, as if they do not belong to F1, but to F2. Once the glitch starts it will persist for any other expanded folder. Any deletion operation will crash dolphin.

The reporter is unsure if this crash is reproducible.

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