Actually you're right, there's something more fishy. Assuming you're running
Xfce, you already run a clipboard manager inside xfsettingsd anyway.

On Linux/Unixes there are two clipboards: the X selection clipboard
(select/middle click), and the GTK clipboard (ctrl-C/ctrl-V or, in terminals
shift-ctrl-C/shift-ctrl-V). They are usually not persistent (if you unselect
or quit the application they're gone), thus the need for a clipboard manager
to handle persistence.

In your case I have the feeling that when the application is quit, the
selection is actually emptied, and it is then propagated to the GTK clipboard.

I'll forward this upstream so they can have a look.
