Error lauching application from desktop icons under ubuntu 16.04 LTS

Hi all,

I just install arduino-1.6.12 under Ubuntu 16.04 LTS

From Term application i can easily launch arduino IDE without any problems
But when I'm trying to launch application from the Desktop Icon, i receive à strange error message
"Erreur lors du lancement de l'application"

Can you help me to resolve this issue ?

Regards,
Lionel
