[Pkg-rust-maintainers] Bug#1120503: Autopkgtests fail: data did not match any variant of untagged enum EitherInterval

Severity 1120503 normal
thanks

I did some investigation.

The tests are all skipped in the version in testing, and doing
some manual testing indicates that this likely affects the
version in testing too.

The cause of the test failure seems to be the downgrade of the
"ron" dev-dependency, This would not be a massive concern,
since dev-dependencies aren't used when the crate is used
as a dependency of another crate.

However, I discovered failure of the test can also be
triggered by updating serde. This was more concerning,
and so I went to file a bug upstream. Before doing so
I did some additional testing, and found that in the
latest upstream git, the test worked with the latest
serde. It seems that updating ron to 0.12 fixed the
test with the latest serde.

My conclusion is it's ok to skip the test for now
(which I have done in the 0.1.2-1 upload) and it
should be re-enabled if/when debian gets ron 0.12.
