The ADO.NET Entity Data Model cannot add stored procedures from a MySQL Server 5.0.45 but it works fine using a MySQL 5.1

How to repeat:
- Create a new Visual Studio Project - Web Site
- Create a new "ADO.NET Entity Data Model" 
- Select "Generate from database" (Click on NEXT)
- Select a connection string to a MySQL 5.0.45 server (Click on NEXT)
- Select any stored procedure in your DB. (Click on FINISH)

On the "Output Window" - "Entity Data Model" you will see the error:

Unable to generate the model because of the following exception: 'Object must implement IConvertible.

And the stored procedure DOES NOT get added to the model.

      - fixed bug where older versions of MySQL would present cast(0 as decimal(0,0)) as string 
        that caused our EF code to throw an exception as it tried to convert that to bool
        (bug #55349)
