Comment (by adamsilverstein):

 [attachment:34350.10.diff]
 * Fixes search results on themes
 * Correct several incorrect uses of _.union (also searched codebase for
 other uses, there were none); added a note to the blog post as well.
 (Since Underscore 1.7.0 "For consistency, _.union and _.difference now
 only work with arrays and not variadic args.")
 * Use a namespaced event `themes:update` vs `update`. Backbone 1.2 Added a
 built in `update` event that triggers after any amount of models are added
 or removed from a collection. This additional unexpected event was
 breaking the search results display on themes.php, switching to a
 namespaced event corrects the issue.
