Bug#909407: pybind11 breaks dolfin autopkgtest

Dear maintainers,

With a recent upload of pybind11 the autopkgtest of dolfin fails in
testing when that autopkgtest is run with the binary packages of
pybind11 from unstable. It passes when run with only packages from
testing. In tabular form:
                       pass            fail
pybind11               from testing    2.2.4-1
dolfin                 from testing    2018.1.0.post1-10
all others             from testing    from testing

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

Looking at the changelog of dolfin 2018.1.0.post1-11, I fear that a
versioned depends or a versioned breaks is missing somewhere. Note that
the Debian migration software considers those to determine if packages
need to be tested together from unstable. If dolfin can't determine the
upper version of pybind11 beforehand, a versioned breaks in pybind11
helps the migration software to use the proper version of dolfin during
dolfin's autopkgtesting. If dolfin 2018.1.0.post1-11 can migrate without
the pybind11 2.2.4-1, you could decide to ignore this bug as once dolfin
migrates, the test that is retried daily will be run with that version.

Currently this regression is contributing to the delay of the migration
of pybind11 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? If needed, please
change the bug's severity.
