    emptyview: Display a message if xdg music dir is not set
    
    If the XDG Music dir, the EmptyView needs to be displayed. However,
    this results in a crash because the _content_text attribute has not
    been set.
    
    This issue is fixed, by setting the _content_text to display a message
    if the XDG music directory is not set.
    
    closes: #338
