I have the same problem with my Artsy MM.....I am soooo angry. The bag is only a year old. The entire top of the bag has small splits all around! It started with one and then just spread. I took the bag to the Louis Vuitton store in NYC and went to the 4th Floor Customer Service and the very rude women there told me that it is a problem they have been having with that bag. She proceded to tell me that the reason it happens is that when you carry the bag over your shoulder your deodorant causes a reaction with the canvas and causes it to split. She told me there is nothing they could do about it. Needless to say, I am not happy. This is my third LV and it has never happened to any of my other bags....
