Package: protobuf
Version: 3.6.1.3-2

Dear Maintainer,
during our build on stretch with backports ienabled with automatic solver
to install dependencies (libprotobuf-dev and protobuf-compiler), pbuiled
aptitude solver managed to install the two packages with two different versions:
libprotobuf-dev = 3.6.1-4~bpo9+1
protobuf-compiler = 3.0.0-9
This leads to broken protobuf toolchain and errors in the build:

Would you consider adding the Breaks dependency (see attached patch)
so the dependency solver is not offered the broken solution anymore?
