Desktop.Open() relies on an xdg-util shell script to open the file.

When the Wait argument is True, Desktop.Open() just waits for the end of 
the xdg-util script. It does not know how to wait for the end of the 
program that will open the file for you.

The Wait argument is mainly useful to catch a possible error when 
running a script. It is not reliable for doing what you want.
