  Target Milestone: ---

Application: dolphin (23.08.4)

Qt Version: 5.15.12
Frameworks Version: 5.114.0
Operating System: Linux 6.5.0-15-generic x86_64
Windowing System: X11
Distribution: KDE neon 5.27
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
On a fresh user, perhaps coincidentally after opening Dolphin in a fish
session, when setting a global theme in System settings, Dolphin appears to
crash. Other odd behavior includes the plasma style not applying and the icon
theme applying in an incomplete fashion.

The crash can be reproduced sometimes.

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