Gobject Introspection update broke dmedia

[Jason Gerard DeRose]

Natty update today broke dmedia. From what I can tell so far, the new GI bindings aren't playing nice with the traditional gtk/gobject bindings. The `dummy-client` script is simple and illustrates the problem. It can be fixed by replacing:

import gtk

With:

from gi.repository import Gtk

(and replacing references to gtk with Gtk). But dmedia seems broken other places to, probably because various `import gobject`. I guess it's as good a time as any to switch the GI bindings wherever possible.

Here's the trace from running `./dummy-client`:

Okay, have confirmed that python-gobject was the offending update.

If I downgrade to pygobject 2.27.90-0ubuntu1 (python-gobject and python-gobject-cairo binary packages), this problem is fixed.
