Up to version 16.04.3 konsole worked as expected and commands like "konsole -e mpv --hwdec=vaapi --vo=vaapi foo.avi" worked without a problem but after the release of konsole-16.08.0 the output of the command is now: "Unknown options: hwdec, vo." it seems konsole takes the -- options and doesn't foreward them to mpv. Reproducible: Always
