I am developing an application with Lazarus 1.8.0RC3, All is ok, apart
from the fact that when the program is launched from a terminal
window, I receive these two error messages :

(scarb:2260): Gtk-WARNING **: Unable to locate theme engine in
module_path: "adwaita",

(scarb:2260): Gtk-WARNING **: Unable to locate theme engine in
module_path: "adwaita",

They are just warning, the program runs correctly, but I would much
like to eliminate them, as they can confuse the users of the
application. 
BTW  'scarb'  is the name of the program.

Thanks

P.S. I forgot to mention that the op.sys. is Linux Kubuntu
