I have been using MySQL Workbench for some time and never had problem with it. But now, I had to format and reinstall Ubuntu and got the 12.04.1 64bits.

After everything was set up as I wished, I tryed to run MySQL Workbench, and when it opens a DB diagram I backed up earlier, it freezes heavily and crashes.

I tryed several things:
- Installed mysql-workbench-gpl avalible from the Software Center;
- Installed the latest mysql-workbench from mysql.com
- Formatted again and installed Ubuntu 12.04 64bits as I had it before.
- Same with Ubuntu 12.04.1 32bits

Nothing helped. Any suggestion? I am currently using Ubuntu 12.04.1 64bits.
