Dear maintainer(s),

With a recent upload of rust-sequoia-openpgp the autopkgtest of
rust-sequoia-autocrypt fails in testing when that autopkgtest is run
with the binary packages of rust-sequoia-openpgp from unstable. It
passes when run with only packages from testing. In tabular form:

                       pass            fail
rust-sequoia-openpgp   from testing    1.1.0-1
rust-sequoia-autocrypt from testing    0.23.0-2
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
rust-sequoia-openpgp to testing [1]. Of course, rust-sequoia-openpgp
shouldn't just break your autopkgtest (or even worse, your package), but
it seems to me that the change in rust-sequoia-openpgp was intended and
your package needs to update to the new situation.

If this is a real problem in your package (and not only in your
autopkgtest), the right binary package(s) from rust-sequoia-openpgp
should really add a versioned Breaks on the unfixed version of (one of
your) package(s). Note: the Breaks is nice even if the issue is only in
the autopkgtest as it helps the migration software to figure out the
right versions to combine in the tests.
