+Summary: XmlElement should not throw exception if constructed with null prefix
+
+The following code throws an exception when run with mono, but not when run
+under Microsoft.NET 2.0 (Windows XP):
+
+-- begin code --
+
+using System;
+using System.Xml;
+
+public class XmlBugTest
+{
+	public static void Main ()
+	{
+		XmlDocument doc = new XmlDocument ();
+		XmlQualifiedName name = new XmlQualifiedName ("Foo");
+		SadXmlElement e = new SadXmlElement (name, doc);
+	}
+}
+
+public class SadXmlElement : XmlElement
+{
+	// If you change the 'null' below to 'String.Empty', this works
+	public SadXmlElement (XmlQualifiedName qname, XmlDocument doc) : base
+(null, qname.Name, qname.Namespace, doc)
+	{
+	}
+}
+
+-- end code --
+
+
+The Exception thrown is:
+
+Unhandled Exception: System.ArgumentNullException: Argument cannot be null.
