LP:706499 - Workbench configuration tabs are empty with MariaDB ( general, etc ... except Performance and Misc )

I have MySQL Server on port 3306 and MariaDB on port 3308.
I can configure them with old gui tools but with the workbench application,
i cannot configure MariaDB because tabs ( general, Advanced, MyISAM parameters, etc ... except Performance and Misc tabs )
are empty, no information.

The workbench application works perfectly with MySQL
I must named the service MariaDB <MySQL MariaDB> under windows for the gui tools administror tool works.

My PC works under Windows XP Home 32 bits with 4 GB Ram CPY Intel Q9650 Disks 150 GB + 300 GB + 2 TB

I install first MySQL 5.1.47 and i used a modified version of MY.INI to configure and install MariaDB 5.2.4
