On some specific GIT tree I repeatedly got e-mails with this error:

PlufErrorHandlerException making GET request to

Some analysis did show that the $blob->content sometimes has only 
two fields, i.e. $tmp[2] (the title) is completely empty. On my PHP 
(5.3.1) this results in an exception. This code did fix the issue:


            $tmp = explode(chr(31), $blob->content, 3);

	    if(!isset($tmp[2]))
	       $tmp[2]="";

            $res[$blob->githash] = (object) array(
                                                  'hash' => 
$blob->githash,
                                                  'date' => 
$tmp[0],
                                                  'title' => 
$tmp[2],
                                                  'author' => 
$tmp[1],
                                                  );
