I will look into it; I would have to create special case for handling null object types which I don't really want, but the sharedPref interface allows it so, I probably have to.

0.4.2 should support null values, as specified by SharedPreference Interface:

Passing null for this argument is equivalent to calling remove(String) with this key.
