[pygtk] windows border problem

[Oguz Yaimtepe]

I have been editing a pygtk application. I added a trayicon property and
activate method for the icon so when i click on the trayicon it will
show and the second click will make the window hide. It works but when
the self.window.show is called i am not able to see the window border.
Can someone check the code and tell me the reason please?
