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].
