I would not be surprised if this were a regression from bug 539356.
Is this a recent regression?
Doesn't crash here.
Probably because bug 539356 was backed out.
Can you check this is, Jesse?
Reason being that Matt wants tests for as many of the regressions from the DLBI bug in the tree as possible, so that Try will pick up failures before he pushes to m-i.
I could add it as a crashtest, but that might not cause it to run with layers.acceleration.disabled.
Some of our tinderbox test machines have layers acceleration disabled, so that's OK.
