Attempting to descend into a string or number would cause a JS error, because we would attempt to create prop[arguments[i]] as an empty object (which is ignored), then try to descend into it (which blows up because it's undefined, even though we've just set it). Guard against this by explicitly checking for non-object-ness. Change-Id: Ie65550baaae0ab88476c9a1ff40cc136090740a0
