I suggest binary-chopping to find the offending changeset. Some early
boot-time stuff went in over the past few days, so for example try reverting
to 16130 and see if that has the same problem. Go back another 30, or
forward 15, changesets depending on whether that works or not. I suspect
this issue is quite new, so it shouldn't take too long to narrow down.
