My best assumption right now is that when multiple Views
contexts are put together, and one doesn't contain any Empty
Text fields, this is triggered.  Changing line 32 of
views_content/plugins/content_types/ from: $block->content =
$output['empty']; to $block->content = !empty($output['empty'])
? $output['empty'] : ''; fixes it; but I'm not aware of where-
else the returned $block's data is used. Should this be array(),
NULL, or ''?   Status:Active» Fixed  A '' is fine. I patched
both 6.x and 7.x branches.  Status:Fixed» Closed (fixed)
