Description:
When I try to get MySqlCommandBuilder.DeriveParameters method with a procedure which have
char type parameter, I throw MySqlException exception with message "Unhandled type
encountered".

How to repeat:
following code
private void addPortalInfo_Click(object sender, System.EventArgs e)
		{
			MySqlConnection conn = new MySqlConnection("SERVER = Localhost;DATABASE = test;UID =
root;PASSWORD =;");
			MySqlCommand cmd = new MySqlCommand("testProc", conn);
			cmd.CommandType = System.Data.CommandType.StoredProcedure;
			MySqlParameter[] discoveredParameters; 
			try
			{
				conn.Open();
				MySqlCommandBuilder.DeriveParameters(cmd);
				conn.Close();
			}
			catch(Exception ex)
			{
				MessageBox.Show(ex.Message);
			}
			discoveredParameters = new MySqlParameter[cmd.Parameters.Count - 1];
			cmd.Parameters.CopyTo(discoveredParameters, 0);
		}

testProc - stored procedure with char type parameter
