            Bug ID: 476010
           Summary: ".cache" After Updates Breaks Dolphin
    Classification: Applications
           Product: dolphin
           Version: 23.08.2
          Platform: Archlinux
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: dolphin-bugs-null at kde.org
          Reporter: kdelovaa at mozej.com

  Target Milestone: ---

SUMMARY
***
On a rolling release, e.g. Arch, Dolphin will be broken, e.g. it won't load
photo thumbnails (e.g. AVIF 5K, which are only a few hundreds Kilobibytes, self
made). After updates all is broken. Removing .cache immediately solves the
problem. KDE should take care of its own updates. Not user.


STEPS TO REPRODUCE
1. Update KDE on a rolling
2. Some apps, like Dolphin may be broken


OBSERVED RESULT
e.g. Dolphin will refuse to display thumbnails of AVIF files.


EXPECTED RESULT
KDE deletes its own cache if its required to properly update KDE. KDE should
know how to update itself. Not an issue of a package manager. KDE created those
files and after updates it refuses to work properly. KDE created these files
and if it created these files and they broke the update then the update
procedure should remove them. Not a distro package manager issue. ".cache" is
xdg, so any update should remove what's necessary to make updates working.
