I don't have the answer you asked for. But I wanted to say that I have noticed that warning since forever and always ignored it. I searched the Internet today and discovered your question has been asked many many times. I didn't paste any links because they are plentiful. There is a fair amount of comment about what it means. But what to do about it, as you asked, was not seen by me today other than "ignore it".
FWIW, playing around with it I discovered that it doesn't always happen...
gedit [file that I own] No
gedit [any file] Yes
gedit [any file] No
sudo gedit [any file] No
Maybe one of the smart guys will tell us what the significance of that is.
