I totally agree with you and also think a good approach is to start with asking the offender if he can help with explaining his code to me so I can understand it well enough so I can change it. Maybe also during the talk ask how he managed to test his code. If I am lucky this will make him understand why it is good to have solid code that others can understand and change without his help. This way I am not directly saying that his code is bad, I am saying I am not able to understand it leaving a possibility that it is me there is a problem with. If the code was written more than 2 days ago he will probably also start having problems with understanding exactly what it do.
