Here is your problem... in GTK+/glib... you want to stay away from
`while (1)'ish code.

try using g_timeout_add() and run "real_estad_fich()" from
the timeout handler (or use g_idle_add()).

You must return to the main loop if you want your app to be responsive
and to update any changes you make (like the statusbar message).
