463168 - Gestures don't work on a newly opened tab before page loads

I've been running into problems with switching tabs by rotating when I'm trying to load california election results pages that are currently very slow to load.

If I cmd-click a link and happen to switch to it by rotating, I can't rotate out of it.

Once the page starts loading, things start working again.

I fired up a debug build and am getting a ton of assertions:
###!!! ASSERTION: Nothing to handle this event!: 'frame', file mozilla-central/layout/base/nsPresShell.cpp, line 5616

of PresShell::HandleEvent

It seems to trigger every time I move the mouse, do 2-finger scrolling, or any gesture.

Assertion originally added in bug 326011.

1) Load http://agadak.net/10sec.php
2) Cmd-shift-click the link (open the same page in a new tab)
3) Move the mouse around and get a ton of assertions

This is happening to me on nightlies. My experience agrees with everything Edward Lee has put forward.
