Package: libcupsfilters2-common Version: 2.0.0-2 Severity: serious
When #1069630 was fixed, libcupsfilters2-common ended up with a Breaks: cups-filters (< 2.0~) dependency.
This is odd, because #1069630 is about a conflict between libcupsfilters-dev and libcupsfilters2-dev, and as far as I can tell, no actual file conflict exists between libcupsfilters2-common and cups-filters.
As cups depends on cups-filters, this doesn't really leave any useful way for libcupsfilters2 to be installed, which in turn renders cpdb-backend-cups uninstallable.
