Inspecting the log with dbus-monitor --session --monitor interface=org.freedesktop.thumbnails.Thumbnailer1 yields "No thumbnailer available for "file:///foo/bar/baz.mkv"", in this case for mkv files. Making ffmpegthumbnailer available to tumbler apparently fixes this. I'm not entirely sure if it should be made a hard dependency, because in theory users can freely pick the backends and at a later time others might become available. I stumbled upon https://issues.guix.gnu.org/37276 where gstreamer has been removed and I don't understand why it's been done. The message only mentions "https://issues.guix.gnu.org/37276", but as I understand it gstreamer was very much necessary because without an appropriate backend tumbler won't show thumbnails...
