https://oneanddone.mozilla.org/tasks/76/ is throwing a 500. New Relic: https://rpm.newrelic.com/accounts/263620/applications/3612614/traced_errors/91164d-1e9e2280-a5ac-11e5-8436-c81f66b8ceca (But there's no stack, sadly, other than "jinja2.exceptions:UndefinedError /oneanddone.tasks.views:TaskDetailView.get" due to 'Message removed by New Relic 'strip_exception_messages' setting'
Thanks Stephen. This is related to bug 1232869 and is being caused by a user deleting their profile. I have fixed the data manually for now, so fix this error, but bug 1232869 should fix it permanently.
Thx Bob - this has gone away now; verified in production.
