With breeze-dark icons theme, that inherits icons for mimetypes from breeze, generic icons (like image-x-generic) are not shown. kiconfinder5 finds such icons correctly: $ kiconfinder5 image-x-generic /usr/share/icons/breeze/mimetypes/file-types/image-x-generic.svg Reproducible: Always Dolphin and KF5 from Git master.
Thanks for the bug report! Do FolderView or the file dialog show the correct icons?
(In reply to Frank Reininghaus from comment #1) Both of them show icons for file-types/unknown.
I cannot reproduce this behavior with Dolphin 17.12.3, the icons show up correctly for me. Can you confirm that this bug is now fixed?
Works correctly with the current git head. Thanks you for looking into the old bug!
Great, I'll close this report then. Thanks for the quick response!
