Strangely, each crash seemed to give TWO crash report windows, and the second window was for the crash from bug 1180561.

Too late for firefox 52, mass-wontfix.

No more add-on, so I don't think this crash can still happen in the profiler.
mozilla::Maybe<T>::emplace<T> is quite generic, in the last month I don't see any of these crashes in the profiler.
