Comment:

 @treibstoff Thanks for reporting this.

 In contrast to most reports of this kind (which are caused by
 plugins/themes ''doing it wrong''), this does actually look like something
 which should be handled/fixed in WP Core in the `wp_widget_rss_output()`
 function.

 It appears that the RSS feed/URL is missing the description element and
 the code looping through the RSS feed items doesn't take that possibility
 into account.
 By the looks of it (based on a quick glance), it also doesn't correctly
 handle the possibility that other expected elements could be missing.

 While it is debatable whether that makes the RSS feed invalid (would need
 checking against the RSS specifications/RFC), I do think WP should handle
 this gracefully.
