Hyracks Data Exception: Could not write frame

Reproduction:
==============
The following query:
for $page_views in dataset page_views
 group by $group_key := $page_views.user with $page_views
 let $morning := for $m in $page_views where ($m.timestamp<43200) return $m
 let $afternoon := for $a in $page_views where ($a.timestamp>=43200) return $a
  return {
 "name": $group_key,
 "count_mornings": count ($morning),
 "count_afternoons": count ($afternoon)
};

Returns an exception message on the web UI result page:
Could not write frame: subplan result is larger than the single-frame limit. 
[HyracksDataException]
