Yes, this is the best approach, since the app might start in a different 
working directory and therefore not find the file.

Note that the working directory can be specified in the .desktop file, or can 
be up to the application's startup code - or the way it's started
(cf. kdeinit and other fork-and-exec launchers).

You mean in case it's relative? The same reasoning applies IMHO.

My code (i.e. KDE) never sends relative paths to the program started via a 
desktop file.
