First occurrence so far, on mozilla-central, in this range of retriggers and backfills

Dana, is there any chance this failure was caused by https://hg.mozilla.org/mozilla-central/rev/3155d983a779ff98645129c066353f3204786f4c ?
Thank you.

Yes, that line was added in that patch. Kershaw - does this indicate a bug somewhere else? Or maybe the assertion isn't always true?

Sorry for the delay.
Yes, that assertion is not always true because we could create a backup connection for fallback connection.
I assume we just need to update that assertion.

I can consistently hit this assert by focusing the location bar, typing addons, and hitting the right-arrow key.
