When testing MDLQA-5441, i've seen that when you show the student outline report, there's an error on the Assignment part.

You can see it on :
http://qa.moodle.net/report/outline/user.php?id=4&course=2&mode=outline

I don't know if it's qa.moodle.net related only, or a general bug...

When i'm on this page, it shows :
