Hi jgart, The patch you sent does nothing and didn't fix your foreign distro. The questions you won't answer were supposed to find out what might have, but let's move on. So, please test ('s suggestion. It's the right fix! Propagation isn't. You can offer two variants of peek (peek-ffmpeg and peek-gnome-shell, say) if you like. I don't think that's necessary, though, unless ffmpeg support is incomplete? Thanks, T G-R
