Hi!
I am having a problem where my CoreData document fails to save. The
problem is most certainly of my making, as it just cropped up.
Trouble is that I can't make much sense of it because CoreData seems
to fail at creating the error message:

Do I have any chance to figure out what is going wrong here?
