I'll back out the offending bug and re-open it. I'll leave this open as well and we'll eventually re-land both at the same time.

Tracking this but Brian can you update this to resolved when you confirm after backout.
Yep. The blocking bug was the one that needed a backout because of this.   It was backed out yesterday, although it hasn't been merged to m-c yet See bug 1026865.
Backout fixed the problem in latest Nightly, so I'm marking this as FIXED looking on Benjamin Kerensa [:bkerensa] comment.
