Open new mode .. open a diagram, add a few objects (I added a layer and an empty table), close the diagram without saving (upper right corner 'x'). 

The diagram icon still displays.  Clicking it returns an error screen. 

Now everything stops working.  I can add a new diagram, but not open it and the same error screen as before keeps pooping up a lot of times.  When it finally stops it cannot open anything. I can open a 3rd diagram but if I do all GUI elements for navigating disappears.

I can not repeat this on Mac OS X. Should try on Windows later.

This issue has been fixed in current release (5.2.29)

An entry has been added to the 5.2.29 changelog:

If an EER diagram was created, and then closed, attempting to reopen it would cause MySQL Workbench to display an unexpected error dialog.
