According to Debian Policy ยง 7.2, Recommends "declares a strong, but not absolute, dependency. The Recommends field should list packages that would be found together with this one in all but unusual installations." https://www.debian.org/doc/debian-policy/#binary-dependencies-depends-recommends-suggests-enhances-pre-depends I think it's plausible that a sysadmin may want to not install thumbnailers to guard against security vulnerabilities similar to the ones publicized in the past year or so by Chris Evans (even though tracker and the thumbnailers have been hardened since). If you disagree, feel free to file a bug against the gdk-pixbuf package. Thanks, Jeremy Bicha
