When using the mysql-connector-net-5.0.0-alpha I run into the folowing error when trying to begin a transaction without specifying the isolation level: 

#42000You have an error in your SQL syntax; check the manual that corresponds to your MySQL server 
version for the right syntax to use near '' at line 1

How to repeat:
DbProviderFactory factory = new MySql.Data.MySqlClient.MySqlClientFactory();
DbConnection conexion = factory.CreateConnection();

conexion.ConnectionString = "server=localhost;user id=root; password=; database=seguridad";

DbTransaction trans = conexion.BeginTransaction();

Suggested fix:
The fix was done in the return statement in line 3 of BeginDbTransaction:

1: protected override DbTransaction BeginDbTransaction(IsolationLevel isolationLevel)
2: {
3: 	return (isolationLevel != IsolationLevel.Unspecified) ? BeginTransaction(isolationLevel) : BeginTransaction();
4: }

Hi Felix and thanks for your problem report.
I was able to verify it with code provided. 
I will just note here that MySqlConnection conn = new MySqlConnection(); works as expected.
