Most interesting, I haven't tried to reproduce, but it does sound
smelly.
I did have a quick peek at some code I suspected but that all seems in

if nobody steps up I guess it'll have to be me, but that also means it
might take a while since I've got some other pending stuff to stare at
before this :/
