This is caused by #41785. I think this should be considered acceptable breakage and fixed unless we see to many other cases, but I'd be okay with a revert decision as well. The diff below fixes this specific case for me.

Hey guys, just to let you know... I'm a bit busy now, but will take care in couple of days.
And no worries, I'm perfectly fine with this ;)

I just pushed version 0.2.1 to crates.io.

Thanks @jsen- . Closing as acceptable breakage.
