ParamSpec TypeError

[Dan Yeaw <dan yeaw me>]

I am trying to convert the etk.docking library to PyGObject to upgrade a 
UML tool called Gaphor to PyGi and make it compatible with Python3. In 
order to do this I need the ability to install child properties.

When I try to create a param spec using GObject.param_spec_float(), it 
creates a gobject.GParamSpec. If I then use this pspec to call 
Gtk.ContainerClass.install_child_property, I get a TypeError since it is 
expecting a GObject.ParamSpec. I also noticed that GParamSpec is listed 
as a static type in GObject overrides module in pygobject.  Is there a 
reason why GParamSpec is listed as a static type?

I have also submitted bug 784991 where I went in to more detail of what 
I was trying to convert. I would really appreciate any help or guidance!

Thanks,
Dan Yeaw
