If you look at the URL - it is crazy long, and seems to have duplicated a lot of info. The duplicated 'order' parameter is apparently the cause of the exception - remove that and it works (but has duplicated columns).

I've tried this in Chrome (while logged in) and Firefox (not logged in) and got the same (though you don't get the traceback if you're not logged in). 

This used to work very recently, I don't know what has changed."	Bug	closed	*.djangoproject.com		Normal	fixed			Accepted	0	0	0	0	0	0
