I try this solution, but if the GTK not find the image I got an error
message on console. Again not work.

On the Bora enviroment I was able to setup the application icon on the runtime.
Now I use the same method and not work, but the problem can be on the
environmante that I use.
So I try to "write" (write ..... simply add a line of code :) ) to
test to set the Icon using C code.
I try to setup the Icon, X-Window-Icon and X-Window-Icon-Dimmed
proerty in .desktop file and the icon is right in the Maemo menu but
is the generic one in the taskbar.
