= bug description =

Whenever the milestone updates page is loaded, there is a TB and an HTTP 500 is returned

= bug analysis =

One of the update filters in !init!.py still references out of date field names for bug objects:

{{{
for bug in update.bugs:
if bug.proposed_blocker or bug.accepted_blocker:
return 'blocker'
elif bug.proposed_nth or bug.accepted_nth:
is_nth = True
}}}

bug.proposed_nth and bug.accepted_nth need to be changed to bug.proposed_fe and bug.accepted_fe, respectively.
