Description:
When working on a EER diagram, creating tables and placing relationships with a table would cause the application to crash under certain coditions.
MySQL Workbench installed from mysql-workbench-oss-5.1.17-1ubu804-i386.deb
What I did:
I created several tables with relationships to one table and then I tried to undo all the process.
What I wanted to happen:
I wanted to have only the first table I've created at the begging, without any relationship or other table in the diagram.
What actually happened:
The application crashed losing all the information not saved.
Output from the console:

Segmentation fault
How to repeat:
1) Add ab EER diagram.
2) Create a table.
3) Add a column to the table. In my case, I added an "id" column with the datatype "INT".
4) Create 4 new tables.
5) Place a new 1:n Non-Identifying Relationship (2) between the empty tables and the table created in the step 2.
6) Undo all the way to the step 3.
7) Undo "Add column 'table1.id'. The application should crash.
