This seems to be a backwards compatibility bug.

I think it's this one.

Hi, this will break on stable tomorrow, with the release of Rust 1.25. @andybarron, can you do a release or at least give someone release rights? I'd also be happy to do that, in this case, add @skade to this repository and skade (florian.gilcher@asquera.de) at crates.io.
