gst-plugins-gio is needed to edit the metadata of music files, without this package rhythmbox is not able to communicate with the needed gst-plugin. Thats ture for rhythmbox-0.12.8 and rhythmbox-2.97, 2.97 prints a correct missing plugin error if you specify "--gst-debug-level=3 --debug" 0.12.8 not. See https://github.com/AdamZ/rhythmbox-magnatune/blob/master/metadata/rb-metadata-gst.c or https://mail.gnome.org/archives/commits-list/2011-July/msg06870.html Reproducible: Always
shouldn't be needed with 2.99.1 as it relies in gst-1, that has this no longer splitted
