iOS Crash On AssetBundle Load Fail

Hi,

We have a problem with a lot of crashes on iOS each time we deploy a new assetbundle for our users to download. We pinpointed the problem (using crashlytics) to the WWW class in the Unity native implementation (WWWConnection.m). However we can't figure out whats the real cause for the issue.

We're using Unity 5.3.6f1
