Jonathan, are you able to reproduce this with e10s disabled?
Flags: needinfo?(jonathan)
Only crashes with e10s

Jonathan,  assuming this is a regression, can you determine the Nightly build this bug first appeared in?
Flags: needinfo?(jonathan)
I can reproduce this. Taking.
Attached patch v1Splinter Review
We expect that if mGestureDownContent is non-null, so should mGestureDownFrameOwner be. And usually those should be the same.
