Enable developer mode, open the terminal (it shows up in the launcher), enter this: "cd /etc/init/apps" and hit enter/newline (that big button on the bottom right of the keyboard :). Then enter "ls", then look for the name of this app's script there. Then you run "devel-su", enter the password (default is "rootme", change it or disable developer mode afterwards!), and after that you run "mv name-of-the-digime-script /home/user/" (this moves it instead of deleting it). Now, REBOOT! Now you can uninstall the app!
Just thought I'd share that here.
