Everything seems to be working fine, except for accessing an HTTPS domain with a self-signed certificate or URL that has an expired SSL certificate. It only crashes on the emulator.

Sorry about that. It looks like the issue was on our end, but it's working fine now.

Here are the error details, this could be a bug within WebKit.
