To reproduce, create a new project and add an Entity Relationship Diagram. Create an Entity and add an Attribute to it, then save the file.

(Saving works fine before adding an Attribute, but fails afterwards)

Thank you for your notice. I will release the fix very soon.

(I will also check the unit tests, this case should be covered by them, but nevertheless they passed.)
