Hello arches, starting with grilo-plugins-0.2.14 (actually 0.2.13), upnp-av USE flag requires dleyna DLNA/UPnP stack to implement media server browsing. This is done through the following collection of packages: * net-libs/dleyna-renderer * net-libs/dleyna-core * net-libs/dleyna-connector-dbus * net-misc/dleyna-server Applications such as gnome-online-accounts, gnome-photos and gnome-music make use of this stack to allow access to pictures and music from your media server locally, though they need you to initiate a search most of the time to avoid excessive loading time. For now, I have package.use.mask'ed the upnp-av USE flag on your arch.
The package.use.mask only applies to ppc/ppc64 and x86. Other arches need to work on bug #521972.
dleyna stack kept unkeyworded and USE masked
