see: rss_cache.inc

start at line 96:

        if ($filesize = filesize($cache_file) ) {
            $data = fread( $fp, filesize($cache_file));
            $rss = $this->unserialize( $data );
            return $rss;
        }

it should be better:

        if (($filesize = filesize($cache_file))>0 ) {
            $data = fread( $fp, $filesize );
            $rss = $this->unserialize( $data );
            return $rss;
        }
