cargo install/build failing with latest nightly

[sophiajt]

On Windows, trying to do a cargo install:

thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', src\libcore\option.rs:323
note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.
stack backtrace:
   0: git_openssl_set_locking

Seems to be okay with nightly-2017-03-03 but recent nightly seems to have issues.

[Arzte]

Seems to be completly broken, for example our travis builds for nightly crash on
cargo --version.

Same error occured in nightly on Windows.
Occured when running cargo +nightly install and also cargo +nightly --version too.

This seems not to be a Windows issue - I'm seeing this on Arch Linux as well.

[devunt]

Using nightly-2017-03-16 seems to be solving the problem. I guess only nightly-2017-03-17 is broken.

$ cargo +nightly --version
thread 'main' panicked at 'called `Option::unwrap()` on a `None` value', src\libcore\option.rs:323
note: Run with `RUST_BACKTRACE=1` for a backtrace.

$ cargo +nightly-2017-03-16 --version
cargo 0.18.0-nightly (4a3c0a63b 2017-03-12)

[devunt]

Found a issue in cargo repo here: rust-lang/cargo#3844.
It also indicates the issue was fixed: rust-lang/cargo#3844 (comment), so closing this issue will be enough.

Duplicate of rust-lang/cargo#3844, but thanks for the report!
