--- Comment #1 from Arturo Borrero Gonzalez <arturo at debian.org> ---
Florian reports that this can't be reproduced in the nf tree.
This seems fixed by d2df92e98a34a5619dadd29c6291113c009181e7 and other commits
in nf which are not merged into nf-next, which is the tree I tested.
So we could probably just close this bug.
