+Summary: assembly name annotation leads to NullReferenceException
+
+Please fill in this template when reporting a bug, unless you know what 
+you are doing.
+Description of Problem:
+
+The mcs compiler crashes with a NullReferenceException on an input file
+that contains an assembly name annotation.
+
+Steps to reproduce the problem:
+1. Create this input file:
+========================= foo.cs =======================
+[assembly: System.Reflection.AssemblyCulture(de)]
+public class Hello {
+  public static void Main (System.String[] args) {
+    System.Console.WriteLine("Hello");
+  }
+}
+========================================================
+2. $ mcs foo.cs
+
+Actual Results:
+Unhandled Exception: System.NullReferenceException: Object reference not 
+set to an instance of an object
