--- Comment #2 from Brent Fulgham <bfulgham at webkit.org> ---
This test uncovered a bug in our handling of Sandbox extensions that only occurs with our test infrastructure.

The TestWebKitAPI (and WKTR) processes are not sandboxed, and it is possible that WebKit clients might themselves be unsandboxed.

When WebKit code linked into an unsandboxed process attempts to consume a sandbox extension, we get a null handle and no error code.

We should treat this as a valid and expected result. I.e., we attempted to consume a valid sandbox extension supplied by a sandboxed helper process, and the Sandbox framework says "I didn't do anything since you are not sandboxed."
