Tried to build iota, a rust editor and got the following error:

Yeah, it looks like you're using a more recent nightly than I am. I'm on 2014-12-20 because the latest nightly is badly broken.

In any case, the fix is backwards compatible. I'm just not sure if there are more bugs. Maybe travis will tell us.

I’ve done the manual fix, iota seems to work well.
