Attached patch Patch for bugSplinter Review
Thanks for the test case Martijn. This patch checks for null on the document's window object before dereferencing it for the top window.

Shouldn't this line (NS_ENSURE_SUCCESS) be removed now?
it shouldn't be removed, it should actually have rv assigned to in the line above. thanks for catching this.

Fixed the typo found in comment #7 on inbound (already made the change to the Aurora patch):
Cannot reproduce the crash loading the test case on Nightly 2012-04-22, Nightly 2012-04-23, Nightly 2012-05-01. Any thoughts ?
Did you have set up Plugins to "Tap to Play" in your settings?
Sorry, I missed that. Able to see the crash on nightly 2012-04-23 with click_to_play pref set on true.
Verified fixed on FF 14b8 on Win 7, Ubuntu 12.04 and Mac OS X 10.6.
