GTK warnings issued when changing state properties on graphics_confirm_window

[Neil Tallim]

It's been confirmed that this problem occurs on fresh Lucid installations, in addition to my primary Karmic and Lenny development environments and my Maverick beta. It seems benign, but it still shouldn't happen, especially since the code is used in much the same way as the about windows.

Any insight into the problem from anyone who has any idea would be welcome. Google's not being particularly helpful.

Reproduction steps:
1) attempt to change screen resolution

/home/flan/projects/quickshot/client/source/./quickshot/gui/graphics_confirm.py:39: Warning: g_object_ref: assertion `G_IS_OBJECT (object)' failed
  graphics_confirm_window.show()
/home/flan/projects/quickshot/client/source/./quickshot/gui/graphics_confirm.py:39: Warning: instance of invalid non-instantiatable type `(null)'
  graphics_confirm_window.show()
/home/flan/projects/quickshot/client/source/./quickshot/gui/graphics_confirm.py:39: Warning: g_signal_emit_valist: assertion `G_TYPE_CHECK_INSTANCE (instance)' failed
  graphics_confirm_window.show()
/home/flan/projects/quickshot/client/source/./quickshot/gui/graphics_confirm.py:39: Warning: g_object_unref: assertion `G_IS_OBJECT (object)' failed
  graphics_confirm_window.show()

The same spate of warnings appear when destroying the window, too.
