Before that I was on 3.12 stable and everything worked, so I guess it
did break in the release which included the aforementioned patches.

That's not what I need to know. Is 4.4.0 broken? If not, then I worry,
if so, then there's not really anything interesting here. Unless 4.6.0
also works. Does it?
We need some help narrowing this down if you want to see it resolved.

Just tested, so 4.4.0 is broken, 4.6 works.

Great, can you use 'git bisect' to find the patch that fixes it?
