The natural response of the human brain is to get angry at the person reporting the bug. Obviously this isn't very useful or logical. A better solution is to think about the problems reported, and decide whether it is a valid complaint or not. Many people automatically feel anger in situations like this, but you can train yourself out of it. It's essentially a kind of mindfulness: you just look at the situation intellectually and watch your emotions, rather than letting your emotions take control.

I would say the only logical time for feeling anger is when someone does something like raping or murdering a member of your family. Even then, anger is only useful in helping you formulate a plan of retaliation.
