[Mono-list] newbie: run-time errors with core dumped in console app

[R.A.M.]

Hi,
I have written simple console program reading data from MySQL database. The
problem is that I receive run-time errors with core dumped.
Here's my program:

using System;
using MySql.Data.MySqlClient;
namespace TestMono
{
	class MainClass
	{
		public static void Main(string[] args)
		{
			const string ConnStr = "Server=localhost;Database=test;";
		        using (MySqlConnection conn = new MySqlConnection(ConnStr))
			using (MySqlCommand cmd = new MySqlCommand(
					"SELECT d.Name Department, e.Name Employee" +
					"FROM departments d INNER JOIN employees e ON d.DepartmentId =
e.DepartmentId "          
                                        + "WHERE e.FireDate IS NULL;",
					conn))
			{
				conn.Open();
				using (MySqlDataReader dr = cmd.ExecuteReader())
					while (dr.Read())
						Console.WriteLine(dr["Department"].ToString(), " - ",
dr["Employee"].ToString());
				conn.Close();
			}
		}
	}
}

Here's database structure:

Table 'employees':
| Field        | Type        | Null | Key | Default | Extra          |
| EmployeeId   | int(11)     | NO   | PRI | NULL    | auto_increment | 
| Name         | varchar(40) | NO   |     |         |                | 
| DepartmentId | int(11)     | NO   | MUL |         |                | 
| FireDate     | date        | YES  |     | NULL    |                | 
Table 'departments':
| Field        | Type        | Null | Key | Default | Extra          |
| DepartmentId | int(11)     | NO   | PRI | NULL    | auto_increment | 
| Name         | varchar(30) | NO   |     |         |                | 

Finally, here's output:

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.

I have copied MySql.Data.dll to GAC and I added reference to copy of
MySql.Data.dll in the project. I don't understand the problem of
System.Transactions because I had no problems with setup of Mono.
Could you help me please? 
Thank you!
