This fixes the python examples in the source to work

Thanks for these

8 - self.set_schema_full (tuple(args), len(args))
9 + self.set_schema_full (tuple(args))

Would be nice if pygobject didn't change something every other version :( Ideally there should be a way to make it work with new as well as old pygobject (doesn't pygobject provide it's version in some prop?)

Since recently there is a gi.version_info that could be used, but its
not available on precsie and I don't know when exactly it was added
(nor when exactly the bindings broke).

So I think there these options:

- simply require latest python-gi and change unconditionally

- I could do a try/except AttributeError but that carries the risk that
it shadows other errors so I'm not really advocating it.

- Something like:

As long as it works on both P and Q, I'm fine with it, we don't need to support every version combination... And +1 for avoiding the use of try except.

Could you also link a bug about this pls?

I think this was fixed long time ago.
