+Summary: When you try to create a XmlTextWriter with a null reference of encoding parameter it throws a NullRefernceException
+
+Description of Problem:
+When you try to create a XmlTextWriter with a null reference of encoding
+parameter it throws a NullRefernceException. In .Net Framework SDK
+documentation says that if a null reference is used the XmlTextWriter will
+use UTF-8 encoding.
+
+Steps to reproduce the problem:
+1. Try to write this program:
+   public class XmlBug
+   {
+       public static void Main()
+       {
+           System.Xml.XmlTextWriter writer = new
+System.Xml.XmlTextWriter("test.xml", null);
+           writer.Close();
+       }
+   }
+
+Actual Results:
+If you run the program you will be prompted with this:
+Unhandled Exception: System.ArgumentNullException: Argument cannot be null
+Parameter name: encoding
+in <0x0018b> 00 System.IO.StreamWriter:.ctor
+(string,bool,System.Text.Encoding,int)
+in <0x00076> 00 System.IO.StreamWriter:.ctor (string,bool,System.Text.Encoding)
+in <0x0012f> 00 System.Xml.XmlTextWriter:.ctor (string,System.Text.Encoding)
+in <0x00032> 00 .XmlBug:Main ()
+
+
+Expected Results:
+No Exception have to be thrown. The XmlTextWriter constructor have to
+assing the right encoder.
+
+How often does this happen? 
+This always happen when i try to use a null encoding.
