With:
  user_pref("layers.force-active", true);

###!!! ASSERTION: Layer already in list???: '!mNewChildLayers.Contains(ownLayer)', file /Users/jruderman/trees/mozilla-central/layout/base/FrameLayerBuilder.cpp, line 2185

Followed by a crash due to too-much-recursion in mozilla::layers::APZCTreeManager::UpdatePanZoomControllerTree.

Sounds not unlike bug 919434.

As suggested by bug 919434 comment 7:

I verified that bug 919144 fixed this, using targeted builds. (Its parent cset, 21df28ade757, reproduces this bug for me -- whereas the cset for the last patch in bug 919144, ff63da70a65f, does not reproduce this bug for me.)

 --> Resolving as FIXED by bug 919144.

(Also: I'm using 64-bit Linux --> broadening Platform from Mac to All)
