--- Comment #1 from Alexey Proskuryakov <ap at webkit.org> ---
I can reproduce with Safari 8 on Mac.

This happens because the web site tries to use either localStorage or sessionStorage (I didn't check which one), and gets into an infinite loop as that raises an exception.

We should probably stop raising exceptions, and provide a fake non-persistent storage when in private browsing.
