Description:
Create model using MySQL Workbench 6.0, upgraded to 6.1 due to bug around sql file reloading in wrong tab.

Now can't export model using MySQL Workbench 6.1, creating new model is fine but exporting any 6.0 model crashes MySQL Workbench.

How to repeat:
Open MySQL Workbench 6.1
Open Model
File -> Export -> Forward Engineer SQL Create Script...
- Output SQL Script File already correct
- Everything unchecked apart from
- Omit Schema Quailifer in Object Name Checked
- Generate Seperate CREATE INDEX Statements Checked
- Add SHOW WARNINGS After Every DDL Statement Checked
- Do Not Create Users Only Export Privileges Checked
- Generate INSERT Statements for Tables Checked
Click Continue
Click Replace
Click Continue
Summary Screen Appears then instantly dissappears and Mac reports crash

Suggested fix:
No idea, can provide model if required but something has failed in the 6.0 to 6.1 upgrade and support.

Please provide the model. Thanks.

Able to recreate issue with new model.

File -> New Model
Add Table "T_REF_ACCOUNT_TYPE"
Column "ID_SEQ" INT PK NN UQ
Column "REF_KEY" VARCHAR(45) NN - Change to 36
Column "REF_VAL" VARCHAR(45) NN - Change to 36
Column "CREATED_BY" VARCHAR(45) NN - Change to 36
File -> Export -> Forward Engineer SQL CREATE Script...
- Everything unchecked apart from
- Omit Schema Quailifer in Object Name Checked
- Generate Seperate CREATE INDEX Statements Checked
- Add SHOW WARNINGS After Every DDL Statement Checked
- Do Not Create Users Only Export Privileges Checked
- Generate INSERT Statements for Tables Checked
Continue

Have restarted mac, have reinstalled MySQL Workbench 6.1, keeps happening.
