A long time ago I was invited to a job interview. After a nice chat, I told them that I had left the previous company because of internal conflicts and too much office politics. I asked if they had the same problem and they assured me that they did not. I also talked about a security breach that defaced our website, but put it in the context of the overall success of our security practice.
In conclusion, I think it's important to be specific about the key negative factor (if asked about) and to frame negative things in a generally positive light, while remaining honest. After all, it's our perceptions and our attitudes that we can change. An interview is not the place to unload your negative feelings. It also helps to remain objective when things get uncomfortable.
