Description

I'm guessing my class that implements OnTrayPreferenceChangeListener is GC'd at one point. I see that the ContentProviderStorage uses a WeakHashMap, but does some other magic stuff (cloning, etc) which perhaps breaks the rule that they key will never be null. Or there's some other problem, I really don't know :O

I have only one registerOnTrayPreferenceChangeListener call, so I can guarantee I never try to call it with null (even if I did, the registerOnTrayPreferenceChangeListener code would catch the null listener)
