I have done the following changes now:In the upstream BZR repo of cups-filters I have removed the now unneeded "Wants=cups.service" from cups-browsed.service (BZR rev. 7474).
In the Debian GIT repository I have added a "Depends: cups-daemon" to the cups-browsed binary package, as cups-browsed is non-functional without cupsd. It does absolutely not make sense to install cups-browsed on a system without cupsd.
