Bug 476010

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.
