Well, I've realized that and AM doing a gtk_widget_show before 
attempting to get the sizes.
But the dialog does not seem to be rendered immediately.

Ooops ... just thought of smth....
What I'm doing is check parameters for an app and pop up a modal warning 
dialog if smth. is wrong.
Now, atm I'm doing this before I start the main loop .... does that 
sound like an explanation?
