Likely registration being null. This is similar to the other flaky crash we know about. My bet is that this is caused by us clearing all registrations between tests. If a registration had a pending install event (or fetch), then when that event completes, we'll come back to the StorageProcess and the registration will be gone by then.

I am hopping https://bugs.webkit.org/show_bug.cgi?id=179774 will fix this.
