Can't unregistering Broadcast Receiver in Android?

I have a broadcast receiver that I try to unregister in the OnPause() method. But then it gets blocked it seems, and although I register it in the OnResume(), it doesn't fire. If I only register it it works well, but then I get the exception "leaking broadcast receiver, you should unregister it", as below:

06-04 22:50:04.267: ERROR/ActivityThread(4188): Activity com.example.android.CView has leaked IntentReceiver com.example.android.CView$1@4062b650 that was originally registered here. Are you missing a call to unregisterReceiver()?

There are tons of posts concerning this, and I have tried many of them without results. The practice is to register it in OnResume and unregister it in the OnPause, right? Or should I unregister it in onStop(). I have tried and then it never listens.

Thanks for any pointers!

Yes. Here is a sample application demonstrating this.
