+Summary: An System.ArgumentException appears when execute any assembly that use PasswordDeriveBytes class
+
+Please fill in this template when reporting a bug, unless you know what you
+are doing.
+Description of Problem:
+
+
+Steps to reproduce the problem:
+1. the source: crypto.cs
+
+using System;
+using System.IO;
+using System.Security.Cryptography;
+
+class Foo
+{
+	public static void Main( string[] args )
+	{
+		Console.WriteLine( Encrypt("go mono!!!", "12345678password") );
+	}
+
+
+	static string Encrypt( string clearstring, string password )
+	{
+		byte[] clearbytes = System.Text.Encoding.UTF8.GetBytes( clearstring );
+
+		PasswordDeriveBytes pdb = new PasswordDeriveBytes( password,
+			 new byte[]{0x47, 0x6F, 0x6E, 0x7A, 0x61, 0x6C, 0x6F, 0x20, 0x53, 0x6F,
+0x73, 0x61} );
+
+		return Convert.ToBase64String( Encrypt(clearbytes, pdb.GetBytes(32),
+pdb.GetBytes(16)) );
+	}
+
+	static byte[] Encrypt( byte[] clearbytes, byte[] key, byte[] iv )
+	{
+		Rijndael rijndael = Rijndael.Create();
+		rijndael.Key = key;
+		rijndael.IV = iv;
+
+		MemoryStream mem = new MemoryStream();
+		CryptoStream cs = new CryptoStream( mem, rijndael.CreateEncryptor(),
+CryptoStreamMode.Write );
+		cs.Write( clearbytes, 0, clearbytes.Length );
+		cs.Flush();
+		cs.Close();
+
+		return mem.ToArray();
+	}
+}
+
+2. to compile: mcs crypto.cs
+3. to execute: mono crypto.exe
+
+Actual Results:
+
+Unhandled Exception: System.ArgumentException: Offset and length were out
+of bounds for the array or count is greater thanthe number of elements from
+index to the end of the source collection.
+in <0x001b5> System.Buffer:BlockCopy (System.Array,int,System.Array,int,int)
+in <0x002a5> System.Security.Cryptography.PasswordDeriveBytes:GetBytes (int)
+in <0x000ad> Foo:Encrypt (string,string)
+in <0x00014> Foo:Main (string[])
+
+Expected Results:
+
+    Encrypt the string.
+
+How often does this happen? 
+Every time
+
+Additional Information:
+The class work fine on .Net Framework.
