This is because that the owner of ~/.config/ibus/bus should always be the user you logged in, and if you use sudo/gksu to run any command this warning will appear but that's expected and please just ignore it. If you removed the file/directory and re-run a command with sudo/gksu, then it will be re-created with the wrong owner, causing further problems in your normal operation.

I get warnings from a couple of programs saying that the owner of /.config/ibus/bus should be what it is currently not. Some say root, some say user. Ho hum. In addition, I have a problem that I believe is related to that. When I log on in the morning, and get my focus in the middle of a blank page, CTL-ALT-Tab does not always bring up a gnome-terminal any more. Sometimes it does, sometimes it doesn't.
