You can reproduce it if you apply this set up to this patch only.
One of the following commits in this set (probably the lavd one, patch
5/7) fixes it.

Bad for bisecting, but it's not like it's the first time it happens.
Still, would be nice if this kind of breakage between patches in a set
can be avoided in the future.
