some python programs in avahi now break with sqlite3 backend in python due to attempts to write to read-only locations. avahi-discover is functionally broken now. i believe upstream is trying to address it in https://github.com/avahi/avahi/pull/698 but it's not in yet. mischief@beast:~ $ avahi-discover (avahi-discover:1600533): GVFS-WARNING **: 22:20:51.707: Error creating proxy: Error calling StartServiceByName for org.gtk.vfs.Daemon: Unit gvfs-daemon.service is masked.
