Application: dolphin (22.04.0)

Qt Version: 5.15.3
Frameworks Version: 5.93.0
Operating System: Linux 5.4.0-107-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.24
DrKonqi: 5.24.5 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Dolphin had 4 different tabs open and closing the fourth tab was the trigger. Not sure what made it special, but it was largely full of executable binary files. Closing any other tab first would allow that one to close without issue and closing ther others seemed to work reliably. Sometimes closing the tab in question would work without crashing, in which case opening another tab and navigating to the folder allowed it to again be reproduced once closed.

The crash can be reproduced sometimes.

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