Trying to track down a null-dereference crash involving Workers and IndexedDB, one possibility is that the generated binding code gets a null context from WorkerScriptController::controllerForContext() and passes this into DOM callbacks (including IDB). It seems unlikely, but we'd like to confirm or refute the hypothesis.
