+Summary: property override breakage in internal class
+
+(I have no idea what the correct summary for this should be -- someone who
+understands what's going on, please change the summary)
+
+The following code:
+
+--- bug30.cs ---
+using System;
+
+public class Foo {
+  protected virtual int SomeProperty {
+    get { return 10; }
+  }
+
+  private class FooPrivate : Foo {
+    Foo _realFoo;
+
+    internal FooPrivate(Foo f) {
+      _realFoo = f;
+    }
+
+    protected override int SomeProperty {
+      get { return this._realFoo.SomeProperty; }
+    }
+  }
+
+  public static void Main () { }
+}
+
+--- end ---
+
+Fails to compile under mcs (cvs as of 4/19) with:
+
+bug30.cs(16) error CS1540: Cannot access protected member
+`Foo.SomeProperty' via a qualifier of type `Foo'; the qualifier must be of
+type `Foo+FooPrivate' (or derived from it)
+
+csc compiles this fine.  This construct shows up quite a bit in nGallery.
