Description:
Workbench rises an error message saying cannot access an disposed object:
Object Name: ModelDiagramForm.

See attached image, after the error occured, a portion of the programs window is not rendered properly (see red lines).

How to repeat:
Start up Workbench.
File - New Model
Model Overview - Add Diagram
Close new EER Diagram
Double click on Model Overview - EER Diagram

Works even with stored Models: double click on Model opens all diagrams, so far so good. Close unneeded diagrams, do some work, open diagram again, boom. Work lost.

An entry has been added to the 5.2.29 changelog:

When attempting to open an EER Diagram by double-clicking it in the Model Overview, MySQL Workbench generated the following unexpected error:

Cannot access a disposed object.
Object Name: ModelDiagramForm.
