           Summary: Dolphin crashes when an encrypted storage device is
                    mounted but dolphin has not been used previously
    Classification: Applications
           Product: dolphin
           Version: 23.04.2
          Platform: Neon
                OS: Linux
            Status: REPORTED

  Target Milestone: ---

Application: dolphin (23.04.2)

Qt Version: 5.15.10
Frameworks Version: 5.107.0
Operating System: Linux 5.19.0-45-generic x86_64
Windowing System: Wayland
Distribution: KDE neon 5.27
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
On a clean installation of KDE Neon (neon-user-20230615-1514.iso), when
mounting an encrypted drive and proceeding to open Dolphin for the first time,
Dolphin throws an error and dies. The relevent error is:

kf.solid.frontend.devicemanager: Couldn't get StorageAccess for
""/home/patrick/.cache/thumbnails/"" - File doesn't exist

Unmount and removing the encrypted drive before opening Dolphin a second time
does not resolve the issue.

Manually creating the thumbnail directory through the CLI does resolve the
issue.

The crash can be reproduced every time.

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