HelloGridView.zip

Follow the tutorial at: http://monodroid.net/Tutorials/Hello_Views/Grid_View

(which is helpfully attached to the bug so that you don't actually have to
follow the tutorial...)

There are two problems with HelloGridView:

1. The linker is busted:

If you enable the linker (currently disabled in the above .zip), build and run
(on an N1 in this case), `adb logcat` shows:

2. There's an apparent bug in the Mono.Android.dll binding, as building and
running without linking produces:
