 It appears that some plugin is using the RSS parsing code in WPMU to load
 RSS data, and the HTTP library being used sometimes provides individual
 HTTP headers as an Array of elements rather than as as String. I haven't
 had much time to track down the error, and fixing the HTTP library is the
 proper fix, but the following quick repair does prevent the error for now:

 /wp-includes/rss.php, ~line 577:

 {{{
 // find Etag, and Last-Modified
 foreach( (array) $resp->headers as $h) {
   // 2003-03-02 - Nicola Asuni (www.tecnick.com) - fixed bug "Undefined
 offset: 1"
   if (is_array($h)) { $h = implode("; ", $h); }
   if (strpos($h, ": ")) {
     list($field, $val) = explode(": ", $h, 2);
   }
 }}}
