In this case I expect the problem to be different environment from when you run 
it manually.

Run your normal desktop session as a different user and try the script manually 
in a shell where you su - into, i.e. so that the current user's environment 
gets discarded.

It might also help to redirect stderr of the application into a file for 
checking if it reported any errors, i.e.
 2> /home/USER/contacts_hourly_backup.err

Kevin
