I saw that error as well, but since debconf also triggers at postinst time again, I deemed it non-fatal.
However, if this is considered a potential trap, then dropping the Conflicts: would work as well (and just keep the Replaces:). I just added the Conflicts: so that belocs-locales-bin would be cleaned up during upgrade, since we don't want to support/use it any more.
