Terminal not starting in Ubuntu 19.04, exo-helper-1 missing

Hello,

When I try to run a terminal from the Applications menu, I get an error:

Failed to launch preferred application for category "TerminalEmulator".

Failed to execute child process "/usr/lib/x86_64-linux-gnu/xfce4/exo-1/exo-helper-1" (No such file or directory).

To reach this point, I made a fresh installation of Ubuntu 19.04 (desktop version),  installed Xfce with sudo apt-get install xfce4, and logged into a Xfce session. My ~/.config/menus/xfce-applications.menu file matches /etc/xdg/menus/xfce-applications.menu.

Selecting "File Manager", etc., from the same top-level menu gives the same error, but it runs from Accessories/Files.

Do you have libexo-1 installed?

libexo-1 is a separate package. It appears to have been left out of the dependencies list in 19.04. Try installing it:

sudo apt-get install libexo-1

...or maybe:

sudo apt-get install libexo-1-0

(don't have 19.04 machine nearby to validate)
