+Subject: Re-allow running Dolphin as the root user (but still not using sudo)
+
+Summary:
+Prohibiting the use of Dolphin as the actual root user (not using `sudo` or `kdesu`) breaks legitimate use cases for using the root user. An example is Kali, a distro that logs in as the root user by default as a deliberate design choice.
+
+In such an environment, there is no additional security vulnerability beyond what you're already potentially exposing yourself to. So, let's re-enable it.
+
+BUG: 387974
+FIXED-IN: 18.08.0
+
+Test Plan:
+- Log in as normal user and run `sudo dolphin`: you get an error message.
+- Log in as normal user and run `kdesu dolphin`: you get an error message.
+- Log in as the root user and run dolphin normally: it works.
