Description:
This is a rather frequent but irregular runtime error that causes a complete crash of the application. I am using the modeling feature currently designing some basic tables following common best practices. 

Occassionally, when i try to open/switch from one table to another (to add a foreign key, or something i forgot) I will get this Runtime Error. It happens exactly when I double click the Model Overview tab on or off of a table I want to open for editing.

It doesn't seem to be dependant on a particular table, but just eventually occurs forcing me to save after every change I make.

It appears the last time it happened the table view opened before it crashed as the table I was clicking on is viewable under the modal dialog.

How to repeat:
Start building a model, quickly switch between different tables. This does not always work, sometimes i have to edit the structure for a while before the crash will occur.

Suggested fix:
Not sure how a purely virtual function could get called, thought that was a compilier checking thing...

Having exactly this same problem, same OS, version, steps to reproduce, etc.  Very difficult to do any modeling - open Workbench, change, save, crash, open Workbench, change, save, crash, etc...
