Sorry, what I meant was "Neither Linus nor I broke it". ie: please report
this in a place where the person who did break it can see it. This you have
done.

I think we'll find that it works OK for hundreds of other people, so it got
broken in some manner which is specific to a very small number of machines,
of which yours is one.
If that theory proves to be correct, I'm afraid that the most proactical
way of fixing this is to ask you to run a git-bisect to find the changeset
which introduced the regression.
