    mime-actions: Fix shift+control+down seg fault on a folder
    
    Using this shortcut on one or more folders causes segmentation fault.
    
    In order to solve this, if there is a directory that needs to be
    activated, the NEW_WINDOW flag is set, so that the initial window will
    be closed and a new one will be created. After a new window is created,
    the CLOSE_BEHIND flag is disabled,so that the window will not be closed.
    The flags NEW_TAB is also set there(unless we want all directories
    opened in new windows), in order for new tabs to open in the newly
    created window.
