[Pkg-rust-maintainers] Bug#976658: debcargo is broken (and the autopkgtest didn't catch it).

[peter green]

Package: debcargo
Version: 2.4.3-2+bw
Severity: grave

After the recent binnmu of debcargo. debcargo update
(after deleting the cache) gives.

> 
>     Updating crates.io index
> Something failed: failed to fetch `https://github.com/rust-lang/crates.io-index`
>

This issue was not caught by the autopkgtest.

In order to check this was indeed caused by the libgit2 update (and not by one of the
other updates that have happened since the last debcargo build in unstable) I did a
test build with libgit2-dev from testing but everything else from unstable. That
test build worked fine.

I suspect rust-git2/rust-libgit2-sys need to be updated to match the new libgit2.

I've got to go now, but I'll try look into this issue some more later tonight.
