Bug 475401

Application: dolphin (23.08.1)

Qt Version: 5.15.10
Frameworks Version: 5.107.0
Operating System: Linux 6.5.0-2-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux trixie/sid
DrKonqi: 5.27.8 [KCrashBackend]

-- Information about the crash:
Debian appears to crash repeatidly when opening it, checking the terminal output I saw it complaining about `~/.cache/thumbnails` not being found:
```
kf.kio.widgets: Cannot read information about filesystem under path "/home/xen/.cache/thumbnails/"
kf.solid.frontend.devicemanager: Couldn't get StorageAccess for ""/home/xen/.cache/thumbnails/"" - File doesn't exist
```
after creating the folder dolphin works perfectly fine.

The crash can be reproduced every time.

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