That seems to be a bug.

Among other things, resourcebundle_iterator_read calls =
resourcebundle_extract_value instead of resourcebundle_array_get (which =
handles fallbacks via resourcebundle_array_fetch).

I'm not sure if the fix is that simple though, as that only fixes =
getting of values, but the iterated range probably still doesn't include =
the fallback values. What would the expected behavior be for iterators? =
Should it iterate over all contents, including fallbacks? You sent =
another message to the list earlier which appears to be describing a =
similar, but different problem where values are null when iterating?
