Thanks for flagging this. I was going to follow up to this bug when it
had aged enough that it would ordinarily have migrated; hopefully it
won't regress this time.

The regression was that the opportunistic dpkg-statoverride during the
preinst, just before the new dbus is unpacked, is too late for that
unpack run to use the dpkg-statoverride info; and because the
dpkg-statoverride entry exists, the postinst wouldn't chmod the binary
either. Installing 1.8.12-2 or 1.9.4-2 for a second time was enough to
avoid that bug, which is why I didn't see this during my local testing.

Removing the preinst's dpkg-statoverride means that the wheezy -> jessie
upgrade will unfortunately still have the non-functional permissions for
part of the upgrade (while dbus is unpacked but not configured), but at
least updates within jessie or from jessie to stretch won't suffer from it.
