* Test for Bug 1339722
* 1. Wait for "http-on-useragent-request" for the iframe load.
* 2. In the observer, access it's window proxy to trigger DOMWindowCreated.
* 3. In the event handler, delete the iframe so that the frameloader would be
* destoryed in the middle of ReallyStartLoading.
* 4. Verify that it doesn't crash.
