When trying to delete a folder which you have no rights to delete it, you will see the error message "Access denied to /home/user/.local/share/Trash/files/$folder". But the given directory is wrong: it should be the directory you want to delete
Steps to Reproduce:
1. mkdir foo
2. sudo chown root:root foo
3. Delete this folder as not root
Error message: "Access denied to /home/user/.local/share/Trash/files/foo."
Error message: "Access denied: /home/user/foo." or "Access denied for deleting /home/user/foo."
Is this still an issue with KDE Frameworks 5.49?
I'm running fedora 28 which packages plasma 5.13.4 right now (afaik). Here this bug is still present. You should be able to reproduce the issue yourself by executing the 3 steps I posted above.
Ah, it's a lack of PolicyKit integration. This should be fixed automatically once Bug 179678 is in.
