You can fix this issue by removing the line "x-scheme-handler/file=exo- file-manager.desktop" from the following files:
/usr/share/xubuntu/applications/defaults.list (provided by Xubuntu) ~/.config/mimeapps.list (user overrides) ~/.local/share/applications/mimeapps.list (deprecated) The entry should not be added anymore according to upstream Xfce [1], and it is the cause for the misbehavior according to the comments in the linked Debian report [2].

It opens only directories, .desktop files and executable files. Trying to open a file, be using Enter or with double mouse click, as a text file or a video makes Nautilus window blink for a instant and nothing happens. To be able to open the files, it's needed to choose to open with another application and then choose the application. Once Nautilus is unset as the default file manager (Thunar is chosen, for example), it starts to work fine again, opening files properly. Nautilus' Debian Sid version do not have this problem.
