Well /.config is a mistake/bug in kde.  They do not set the default homedir, and are writing a random file/directory into the / directory.

Since the command wants to write to the /.config directory, it should have permissions 755 which is causing the DAC_OVERRIDE problem.

chmod -R u+w /.config

Should eliminate the DAC_OVERRIDE request.
