foreach() error in feedmanager.module

line 665 of feedmanager.module generates an error when it encounters an empty feed (one with no items currently in it, not one with no content):
Invalid argument supplied for foreach() in ... /modules/feedparser/feedmanager.module on line 665.

this isn't something most people run into (how many feeds do you know that don't have any posts?) but is a fairly simple fix. i added this line just before 665:
if (!isset($feed['items']) || !is_array($feed['items'])) $feed['items'] = Array();
