Build is failing

[hannobraun]

The Travis build has been failing since the weekend. This is caused by a bug in Rust: rust-lang/rust#18775

There's an open pull request to fix the bug: rust-lang/rust#18811

Thanks to @jakerr the original problem has been fixed! Thanks again!

I'm leaving this open because the build still fails for unrelated reasons. This should be quite easy to fix and I'll do it soon, unless someone else gets to it first.
