The python2 dependency on gconf2 binary package is due to the fact that migrations scripts are using #!/usr/bin/env python, which is what was adviced by the ubuntu python maintainers so that the day default python is changing, we'll get the correct default version.
dh_python3 is then, adding this python2 dependency. It means that day python3 is the default, a simple package rebuild will be needed.
Considering back this bug as "fix released" as nothing has to be done in gconf itself.
