[iOS] Random crash at launch

Hello!

We have random crashes number increased with latest 4.0.1 library, was 3.x.x before but also crashed from time to time.

This version gives us ~200 crashes in just 2 days.

The logic is simple: app launches, loads webview, we got some cookie as signal to update (resetIdentity) Zendesk instance. Then crash.

Any ideas ?
