The last line of this method is returning nil when Owner3 is nil.  I'm
not sure what that code is trying to do, but try throwing some more
parentheses in it, or an old-fashioned "return owner_array". Also
check out Array.map/collect (map and collect are aliases) and
array.compact, they might do what you want already.
