 The checks if a query var is set are a bit inconsistent: sometimes it's
 `'' != $qv`, other times it's `! empty()` or `isset()`. Looks like an
 unset may not always be appropriate.

 [attachment:17737.5.patch] adds an `is_array()` check to some existing
 conditions and assignments that cause a notice.
