[Pkg-rust-maintainers] Bug#942243: dh-cargo breaks rust-globset autopkgtest

Dear maintainers,

With a recent upload of dh-cargo the autopkgtest of rust-globset fails
in testing when that autopkgtest is run with the binary packages of
dh-cargo from unstable. It passes when run with only packages from
testing. In tabular form:
                       pass            fail
dh-cargo               from testing    21
rust-globset           from testing    0.4.4-1
all others             from testing    from testing

I copied some of the output at the bottom of this report.

Currently this regression is blocking the migration of dh-cargo to
testing [1]. Due to the nature of this issue, I filed this bug report
against both packages. Can you please investigate the situation and
reassign the bug to the right package?
