If I make a complaint about my colleague to my boss, will it make me look weak?

I'm the deputy editor on a magazine and the editor is completely disorganised and an absolute nightmare to work with, as well as being really dishonest to me when I discover she has made certain errors. I have covered for her mistakes and blunders for well over a year and I don't think it's fair that I do it anymore. I've even filled up a notebook with diary entries for months on end to keep a record of all the ways she has messed things up. I really want to make a serious complaint to our publisher but will I look like a tell-tale or come across as someone who can't cope with the pressure? Help!
