This bug was filed from the Socorro interface and is report bp-b9e1c64a-9714-4651-93ff-730622160405. ============================================================= Nightly build 20160405030214 has 6 crashes like this one, making it the #2 cause of crashes for that build at the time of writing. In UpdateInterpositionWhitelist() is looks like |interposition| is null. The caller (XPCWrappedNativeScope::XPCWrappedNativeScope()) asserts that |mInterposition| is not null before passing, but maybe it's happening anyway? Perhaps a proper check rather than an assertion would fix this.

It appears to be a startup crash. All the uptimes are 0 or 1.

Most of the crashes were marked as dupes of one of them so I'm going to mark this as backlog for now.
