+Summary: 'params' in DllImport function does not work
+
+Description of Problem:
+Trying to use a native function that accepts variable argument list does
+not work.
+
+
+Steps to reproduce the problem:
+1. Just compile and run this program.
+----begin
+using System;
+using System.Runtime.InteropServices;
+
+public class MyClass 
+{
+	[DllImport("glib")]
+	static extern int g_print (string format, params object [] o);
+
+	public static void Main (string [] args)
+	{
+		string name = "Gonzalo";
+		int randomNumber = 69;
+
+		g_print ("Hola %s. Viva el %d!\n", name, randomNumber);
+		g_print ("Ejem!\n", null); // See comments below
+	}
+}
+----end
+
+Actual Results:
+If i don't add the 'null' as argument to the "Ejem" g_print it crashes:

+Expected Results:
+Hola Gonzalo. Viva el 69!
+Ejem!
