...because l is still NULL, and g_list_length(NULL) is 0.   
g_list_append returns the address of the first item in the list  
with its appended item, so you should use:

      l = g_list_append(l,GINT_TO_POINTER(1));
      l = g_list_append(l,GINT_TO_POINTER(1));
      l = g_list_append(l,GINT_TO_POINTER(1));
