I'm a developer myself and I absolutely oppose this practice. I don't do it and I don't want others to either. The possibility of exposing sensitive information is just not worth it. If you discover a bug you can always make a bug report and provide any details there. In that case, the consent and scope of disclosure is made very explicit. Chances are you don't know what information a machine-generated bug report contains, but you do know what you wrote when you reported it.
