By jean:

From `AddThisViewlet.chicklets` it doesn't look as if `chicklet` should ever be false.
It could be false if the `addthis_chicklets` property contained an empty line, and `vocab(self.context)` returned a term with a blank string as `name`. That seems like a degenerate case to me. If it can't be prevented from happening, it can be stopped in the view:

chicklets = [term for term in vocab(self.context)
if term.value and term.value in chicklet_names]
