Expected behavior:
The Player selected as standard opens with a playlist of the (media)files.
(This is what actually happens if you select an application with the open with ... dialog)
What happens:
Nautilus launches for each file a separate instance of the standard-application.
Example: 10 mp3 files selected opens 10 player-windows of audacious, qmmp, vlc, mpv or what ever is selected as standard. (I did try all of the named programs)
This happens only if the group of files is open via pressing Return or selecting 'open' in context-menu. It does not happen when selecting an application via 'open with ...' in context-menu.
Same behavior with groups of png or jpg files and photo-viewers.
Reconstruction:
1. Open Nautilus
2. Set a mediaplayer as standard-application for mp3-files.
3. Open a group of mp3-files by selecting them and pressing 'Enter' or using the 'Open'-Item in the context-menu
