Well aside from some of the obvious ones mentioned in the OP that I'd imagine would be close to universal.
1:Anxiety/ self-confidence issues: Just because of bad experience involving a very clingy ex who was always anxious that I would leave her, which lead to some pretty big issues which I'm not willing to discuss in this thread; It's kind of unfair to other people who have more minor issues, but I'm very turned off by angst now.
2:Excessive drug use: If somebody is a casual user of a drug, I don't care, but it's a deal breaker if it's a lifestyle for them.
3:Snobby attitude: Too much confidence can be a bad thing; I don't like people who hold themselves too highly.
4:Having a problem with my female friends: I have friends, some of them are female, I'm not going to stop associating with them because my girlfriend doesn't like that.
5:Taking issue with my hobbies: They don't need to have any remote interest in my hobbies, but if they have an issue with my hobbies or think less of me because of them, it's not going to last long.
(ie. I'm not going to hide my 'geekyness' from a girl)
