+Summary: Compiler gives odd response to a logic error
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+I came across this compiler error when I made a very silly mistake in my 
+logic while seeing what I could do with the new improved Mono.
+
+Here is a sample of what kind of code I was trying to compile:
+
+using System;
+using CustomAssembly;
+
+namespace App
+{
+    public class App
+    {
+        CustomClass blah = new CustomClass();
+
+        static void Main()
+        {
+            blah.Username = "test"; //This is the logic mistake
+            Console.WriteLine("Test");
+        }
+    }
+}
+
+Actual Results:
+Here is the mcs compile results:
+
+(process:29973): ** WARNING **: unhandled exception 
+System.NullReferenceException: "A null value was found where an object 
+instance was required"
+in <0x0016b> Mono.CSharp.FieldExpr:Emit (Mono.CSharp.EmitContext)

+in <0x018e6> Mono.CSharp.Driver:MainDriver (string[])
+in <0x0000b> Mono.CSharp.Driver:Main (string[])
+
+Expected Results:
+Maybe a nicer error outputted so the person can understand the mistake 
+they did?
+
+How often does this happen? 
+Every time.
