Bug 481860

Application: dolphin (23.08.4)

Qt Version: 5.15.12
Frameworks Version: 5.115.0
Operating System: Linux 6.7.5-1-default x86_64
Windowing System: X11
Distribution: "openSUSE Tumbleweed"
DrKonqi: 5.27.10 [KCrashBackend]

-- Information about the crash:
I launch Dolphin and navigate to the folders and locate files. Operation is fine during this launch.
However, if I leave it alone for 30-60 mins I notice that the RAM usage has jumped from 26% to 40.1% (in my current example).
I have mapped an NFS share so that I can access files on my separate NAS, and there appears not to be an issue navigating that share. It is only when Dolphin is left alone without any user interaction that it seems to gobble RAM, before then crashing!

The crash can be reproduced sometimes.

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