Logs don't show on try results page

https://dart-ci.firebaseapp.com/cl/137060/2 shows "Logs" popups that are empty (No links).

Seems to be some sort of NPE:

stacktrace.dart:60 EXCEPTION: NoSuchMethodError: method not found: 'c' on null
STACKTRACE:

Maybe this is because this is a new configuration?
