/**
* Test for Bug 1339722
* 1. Wait for
"http-on-modify-request" or document-on-modify-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
* destroyed in the middle of ReallyStartLoading.
* 4. Verify that it doesn
't crash.
