Delegate callbacks should never be called with a null web view. I think you should try to figure out why it is null instead of adding a null-check.

Ok, thanks for reviewing :) I will investigate why it happens.

Even though Anders doesn't like this check and return, it definitely seems like we should ASSERT here (or maybe even RELEASE_ASSERT?) so we can catch when this happens.

Thanks :) I will add the ASSERT, and see if I can find the cause.
