"int" maps to the same underlying type in Python 2 and Python 3. This wasn't changed when pygobject was ported to Python 3 and can't really be changed now. If you want be sure your numbers fit use the suggested "GObject.TYPE_*", or just use "object" which means the Python int object is stored as is, assuming you don't need to access it in C code somewhere else.
