Error when trying to create milestone with existing name

[finn@…]

If you try to create a new milestone with the same name as an existing one, you get a python error message and traceback. This should be handled gracefully with an instruction to the user about choosing another name.

Traceback (most recent call last):

Right, the problem is still there.
