As Larry said, GetDataBrowserItems() expects an allocated handle (it
will resize it to match the number of items returned).

Handle h = ::NewHandle(0);
::GetDataBrowserItems(browser, kDataBrowserNoItem, false,
kDataBrowserItemIsSelected, &h);

If I remember correctly, OS X doesn't like handle sizes set to zero. I
am not 100% sure about this

I can't say I've ever had issues with 0 sized handles on OS X. However,
there are differences in how 0 sized pointers may be dealt with
depending on OS (at least as I'm remembering in the past) as some
libraries return NULL while others return a valid pointer.
