Hi Sean -- Can you find someone to look at this?

longsonr - Thank you for the patch.

Pushed by longsonr@gmail.com: https://hg.mozilla.org/integration/mozilla-inbound/rev/42f0da322d14 Fix asertion failure when lengthAdjust value is empty r=heycam

Do we want this in beta63?

I don't think we need to bother
